The spiritual disciplines: solitude and silence

Published October 24, 2017  ·  All posts on Oct 24  ·  

The need for silence and solitude obviously seems incredibly relevant to the over-convenienced citizens of the modern world who feel saturated with the ceaseless noise that issues from every corner of their lives. But as mentioned at the start, men have in fact craved these states for thousands of years, long before anything digital, or electronic, or urban ever existed.

What accounts for the timeless, seemingly universal appeal of quiet seclusion?

I strive to be a Stoic

Published October 20, 2017  ·  All posts on Oct 20  ·  

“When cynicism becomes the default language, playfulness and invention become impossible. Cynicism scours through a culture like bleach, wiping out millions of small, seedling ideas. Cynicism means your automatic answer becomes ‘No.’ Cynicism means you presume everything will end in disappointment.”

Caitlin Moran on Fighting the Cowardice of Cynicism – The Marginalian

slip:4ubaca2.

I am not a Cynic. (…but 10 years ago, I think I was well on my way to becoming one.)

I strive to be a Stoic.

Everyone, (that I’ve ever asked for a definition,) uses the adjective “stoic” to mean: unfeeling, uncaring, showing no emotion. While it’s true that words mean whatever we all agree they mean, in the case of “stoic” that definition is a drastic change of focus from what the Stoics (a group of Philosophers both ancient and modern) are doing and thinking.

Can we back up a layer to find some common ground?

You’d probably be ok with this definition:

“stoic: adj. Of, or relating to, the school of philosophy, Stoicism, founded by Zeno, …”

…but then everyone seems to rush off to this definition of Stoicism:

“[… Zeno,] who taught that people should be free from passion, unmoved by joy or grief, and submit without complaint to unavoidable necessity.”

…and that’s where I disagree.

That’s a poor definition, because Stoics (the Philosophers) do feel, do care and do show emotion. In fact, one of the key points of Stoicism is to feel, care and show emotion in appropriate ways and to appropriate degrees. Stoics grieve, express joy, etc. They also understand the difference between things within and without their control. Described that way, doesn’t Stoicism sound pretty sane?

Now, I am a Philosopher, by definition, because I try to apply Philosophy to my daily life. But, I am not a teacher of Philosophy.

My hope?

That I’ve piqued your interest enough that you’ll go read this “Stoicism 101” about how to use the Stoic Philosophy today, to improve your life:

Freedom is the capacity to pause; Your list of three people

Published October 13, 2017  ·  All posts on Oct 13

Freedom is the capacity to pause in the face of stimuli from many directions at once and, in this pause, to throw one’s weight toward this response rather than that one.

The pause is especially important for the freedom of being, what I have called essential freedom. For it is in the pause that we experience the context out of which freedom comes. In the pause we wonder, reflect, sense awe, and conceive of eternity. The pause is when we open ourselves for the moment to the concepts of both freedom and destiny.

§6 – Sleep Epilogue

Published October 7, 2017  ·  All posts on Oct 7

This entry is part 6 of 13 in the series Changes and Results

Here are a couple more things which I’ve read about, but haven’t tried as part of my sleep hacking.

Sleep journaling

Some people have suggested keeping a sleep journal. In it you record everything related to sleep: notes about your last meal (what and when), what time you go to bed, when you wake up, perceived quality of sleep, dreams… everything. You would then be able to review this sleep journal periodically and use it to inspire changes in your sleep rituals.

The best way to improve you sleep is to conduct experiments. Change some detail and then sleep with that for a month. Then review your sleep journal notes to compare with the previous month.

In my general life hacking, I was often changing many things at the same time. Some of the details of sleeping which you would hack on with a sleep journal, I was already hacking and tracking.

Sleeping alone

My Grand-parents’ generation seems to have slept more frequently in separate beds than is popular these days. (A quick search of the Internet leads me to believe as many as 1/3 of couples currently sleep in separate beds on a regular basis.)

I haven’t graduated to this level, yet. But I can tell you that having another person immediately next to you whose movements, or snoring, may wake you, is just another thing to mess up your sleep. When I first started hacking my sleep, I realized that we were waking each other up frequently in the night. It turns out that if I’m only sleeping lightly, the other person’s movements will wake me. But it seems that as my sleep quality has improved, movements and sounds are now much less likely to make me.

That said, if you wanted to try separate sleeping, you could try sleeping on the floor (with futon cushions, or air mattresses.) You could then move your bedding closer or farther apart as the mood strikes, and still be on a solid surface which would not convey any sense of movement from the other person. You’re still close enough, of course, that sounds could be an issue.

Aside: This is one reason why I prefer to sleep on my air mattress on the floor when I travel. Sharing a pull-out sofa or large bed with someone I don’t know, is the worst-case scenario for being disturbed all night.

How the brain really works, butterflies

Published October 5, 2017  ·  All posts on Oct 5  ·  

The key insight: the brain is a multi-layer prediction machine. All neural processing consists of two streams: a bottom-up stream of sense data, and a top-down stream of predictions. These streams interface at each level of processing, comparing themselves to each other and adjusting themselves as necessary.

~ Scott Alexander from, Book Review: Surfing Uncertainty | Slate Star Codex

slip:4usabo2.

This seems to be rocking my world. There’s an actual theory of how the brain works?

So we are likely getting more lead, more omega-6 (and relatively less omega-3), and less lithium than people in 1850. If there has been an increase in crime and other undesirable/impulsive behaviors, I think these biological insults are at least as worthy of examination as political changes that have occurred during that time.

Back pain

Published September 25, 2017  ·  All posts on Sep 25  ·  

This entry is part 63 of 72 in the series My Journey

Somewhere in my 30’s, slowly, year by year, the frequency of my back problems increased. I’m not talking about, I helped a friend move over the weekend, or, I did climb-ups for an hour at Parkour class, and now my back is “out.” I’m talking about,

I sat down to put socks on — because I cannot hold my foot up to reach it standing — and my lower back “just” gave out.

or,

I was just standing at the sink washing dishes.

For me, these incidents where I was clearly not doing anything amazing and was still somehow injured, became a clear sign that I needed to change something. In hindsight, this is the article I wish I had found first and so I hope it helps someone.

Elsewhere, in my Changes and Results series, I’m laying out all the big things I’ve changed, project by project. But there was never any one thing that I worked on specifically to fix my back. It simply turned out that many of the things I did contributed to — knock on wood — resolving my back problems. Of course my back still gives me trouble when I deserve it. But these days, I know when it’s going to be a problem. I can feel when my back is getting tired, and if I listen to that quiet signal I can avoid the worst of the problems.

My spine and me

Although I had been doing some intentional, general improvement efforts, such as losing weight and getting better sleep, my back-focused improvement journey really began when I heard Ido Portal say something to the effect of:

Your legs are for moving you through your environment. Your arms are for manipulating your environment. Your spine is for orienting yourself within the environment. So your spine should be this incredibly mobile and powerful system with a huge range of dynamic movement.

(That’s not an exact quote because I don’t feel like going through the entire “Rewild Yourself Podcast” episode where Daniel Vitalis interviewed Ido Portal. It’s episode number 8: Ido Portal on the Movement Diet which you should probably go listen to.)

When I heard that, I realized that my spine was nothing at all like Ido’s vision of a human spine. Mine barely moved at all, and when it did, I often felt nervous about impending disaster. After hearing Ido’s way of describing the spine, I had this new perspective where each time I’d do some movement, I could see how much my spine was right at its limit of ability. I realized that my spine should be an incredibly varied mover, and that my spine’s flexibility (the total movement possible) and range of motion (the smaller space of movement where my back is usable, comfortable and strong) are critical, foundational elements to all of my health and movement.

I realized that for years I had tried to “stabilize” and strengthen my spine as a defense against movement causing injury to my back. But I now see that this is an erroneous reaction to weakness. If instead of being immobilized as a defense, my spine is strong, then it can be mobile, able to make all the movements I need, and not be injured.

Awareness and honesty

The first step was to learn to avoid injury. This sounds trivial, but it was not at all obvious to me at the time. When I was so fat and inflexible that putting my socks on regularly endangered my back, it was a terrible, humbling experience to admit that I had to change how I put my on socks.

I had to identify all the landmines, and own up to them. I had to learn that stretching — really just moving around — was mandatory each morning. I had to stop automatically rushing to help everyone move heavy objects. I had to stop trying to be “the strong guy,” and generally dial down all my activities to a level my back could handle. I had to acknowledge those random days when my back felt “off”, and learn to take a rest day for recovery.

All of which forced me to face that I was no longer indestructible and to own up to the deteriorated state of my body. Awareness and honesty were the only way that I could stop taking frequent steps backwards. They were the only way that I could begin to make glacial forward progress.

(I’ve written more about the Philosophy of the changes I’ve made in my Changes and Results series.)

Weight loss

Losing weight is obviously not easy. But every pound that I peeled off paid dividends to my back. It turns out that weight around your middle drastically increases the load on your lower back. “Lost weight” is a woefully inadequate summary for this element of fixing my back, but hopefully I’ll get around to writing out everything I did to lose weight.

Recovery work

What began as endless massage work by my spouse, slowly morphed into self-massage and then into mobility work; Basically, I learned to lay on the floor moving in all the ways my spine was meant to move. I mastered the use of a foam roller and Lacrosse ball for myofascial release and self-massage. As my back got stronger, I was able expand this recovery practice to a more general, whole-body movement, stretching and — much later — general strengthening.

(I’m writing a separate post on my “20 minutes of morning stretching” which is one of the cornerstones upon which I have built the whole new me. It’s not yet published, but will eventually be part of my Changes and Results.)

Finally, chiropractic has saved me countless times. I know many people who believe chiropractic is quackery. But for me, it doesn’t matter how or why, it simply yields results.

Posture

Years of sitting, and progressive weakening of my back, took their toll. Worse, the hunched back, rolled shoulders posture was so common in my environment, that it seemed normal. So I didn’t even realize what was happening to me.

The first baby step to improving my posture was when I learned how to understand, and control, the orientation of my pelvis through learning to sit as part of martial arts training. The traditional Japanese seated posture, seiza where you sit with folded-under knees and pointed toes is great for learning posture. Of course, this type of sitting initially rewards you with agony from the knees and ankles. But once your legs adapt, there is a delightful feeling of peace and centralized weight when you learn to center your pelvis and to balance and align your entire spine. But maintaining this alignment, even in a statically balanced seated position, required a certain muscle tone. A tone which I had lost through endless sitting in a poor posture.

I soon realized that the orientation of the hands as they hang at your sides is indicative of your upper back posture. Palms turned to the back, (the shoulders being in interior rotation,) with that “knuckle-dragger” appearance is a sign of a week upper back and poor scapular position. I began incorporating various exercises, (the ‘Sphinx’ pose from yoga, ‘shoulder dislocations’, and thoracic extension in supine position, etc.) into my daily recovery work. (For a great introduction, read De-Quasimodo Yourself.)

As I’d gained weight, I hadn’t realized that I had also, slowly transitioned to a “dumped” lower abdomen: guts hanging out the front, pelvis tipped forward, and lumbar spine pulled forward into a maximum arch. This led me to lower back agony whenever I spent time on my feet, especially if I over-worked my lower back by strolling and slowly shift my weight from one leg to the other. But as I’ve lost fat from my typical abdominal male pattern, and as running and jumping in the context of parkour have strengthened my glutes, it has become easier to maintain a neutral pelvic position and a neutral curve of my lumbar spine.

Walking

Solvitur Ambulando ~ It is solved by walking

Today, I have a ton of stuff here on my site about walking.

But it all started, long ago, when I read a blog post by Steve Kamb, about Walking to Mordor. “One does not simply walk into Mordor!” Except, that is exactly what Sam and Frodo did. Elsewhere I’m writing an entire post about my efforts and progress related solely to walking; But all of my walking was kick-started by Steve’s Nerd Fitness blog post.

Shoes

This was the least obvious thing which improved my back: The closer I get to living barefoot, the better my back feels.

Long ago, I was wearing “normal” shoes, and then I started taking some parkour classes. Turns out that I want to wear the lightest weight, and thinnest soled, shoes I can; because I want to use my feet and toes. Anyway, roll with me here when I say: I wanted to wear minimal footwear for parkour. So, I started wearing Feiyue shoes to class — not the fancy French brand of shoes, but the el’cheapo, crépe sole, martial arts shoe. They have no structure, no arch, and just some padding and protection from most (not all) things you might step on.

I started to run in Feiyue. I ran 10 feet and my calves cramped up. I kept at it. For years. I relearned how to run. Then I relearned how to walk. Then I relearned how to use my knees. Then I realized that to get things working again, I needed to stop wearing “normal” shoes entirely. So I started wearing Feiyue everywhere.

I went on reading about feet. …and about minimal shoes. …and about barefoot training. Then I learned about the amount of nerves in our feet, (the same as in your hands,) and I had some discussions about sensory input through your feet. …and balance. …and acupressure points.

It is not an exaggeration to say that learning about my feet has changed my life.

Today, I exclusively wear an old-school track running shoe called Bullets, made by Saucony. I remove the insoles, so that from the midsole to the toes there is ZERO padding; just a few millimeters of hard rubber sole between my foot and the world. I wear these same shoes for everything. All surfaces, all activities — everything.

The ah-ha moment

It was at this point — after all of the above changes, and after I had spent about two years full-time in minimalist shoes — that I realized my back was fundamentally different.

Then I set out to write this, over the course of 18 months. :)

Chris Keighley: Challenge, personal growth, and 1,000 muscle-ups

What can we learn about personal growth, resilience, and community through extreme physical challenges?

Chris Keighley helps me muscle up the strength to understand challenge. We discuss its rewards, hazards, and how it can be a powerful tool for personal growth from day one. He shares stories from behind the scenes of the 1,000 Muscle-Up Challenge, and talks about finding challenge in more mundane activities, like building a tire tower at the Gerlev International Gathering.

Modern life doesn’t give you many chances of seeing what you’re capable of.

~ Chris Keighley (6:30)

The conversation centers on the 1000 Muscle-Up Challenge, an intense physical and mental test. The origins of the challenge, its evolution from a hypothetical debate to an actual event, and the experiences of participants highlight themes of resilience, camaraderie, and self-discovery. Chris navigates physical exhaustion and mental roadblocks, supported by a tight-knit community, ultimately revealing their limits and potential.

Other topics include the broader philosophy of challenges in parkour and training. The discussion explores how setting appropriately difficult challenges helps individuals grow, with parallels drawn between physical challenges and life experiences. The importance of community support in such endeavors, as well as the transformative effects of overcoming personal boundaries, are recurring themes.

Takeaways

Challenges and growth — Difficult challenges reveal untapped potential and build resilience.

Camaraderie in struggle — Support from others transforms individual challenges into shared victories.

The mental aspect of training — Mental endurance is just as crucial as physical strength in overcoming obstacles.

Personal limits and discovery — Pushing beyond known limits fosters personal growth and self-awareness.

The role of uncertainty — Effective challenges must be within reach but not guaranteed, encouraging full effort.

Value of small challenges — Even minor challenges, like balancing exercises, can be deeply rewarding.

Physical risk and wisdom — Extreme challenges require careful judgment about safety and personal limits.

Adapting training — Different challenges suit different stages of experience and capability.

The joy of overcoming — Achieving difficult goals provides a profound sense of accomplishment and pride.

Podcast, interview with Jerzy Gregorek

Published September 21, 2017  ·  All posts on Sep 21

I just finished listening to Tim Ferris’ interview of Jerzy Gregorek. The Lion of Olympic Weightlifting, 62-Year-Old Jerzy Gregorek (Also Featuring: Naval Ravikant) (#228) – The Blog of Author Tim Ferriss (episode from March of 2017)

slip:4utije1.

It’s a very long podcast, but I really enjoyed getting to know Jerzey. Around 2h39m in, as they’re wrapping up, he says…

I see that the first 50 years is your first body, but also it is “nature versus nurture.” So you have the nature; you use the body, but you don’t care. The body is fantastic, it is restoring itself, it is recovering itself, and it is very, very forgiving. The next 50 years is the nurture. It’s time to be intelligent, it’s time to have goals, it’s time to have plans, it’s time for that. So if we start nurturing the body we can easily go for another 50 years, right? So that’s our second body. There is this gracefulness on the road that we need to learn. Once you get that gracefulness then your journey can be pleasant, your journey can be proressive and your journey can be joyful.

~ Jerzey Gregorek

I’m not quite 50, but this really resonated with my recent [several years worth] work, efforts, journey and progess.

Update Oct ’17:

Link to Jerzey’s “Happy Body” book which I’m really enjoying. He has a very direct and simple way of defining, measuring and working towards a happy body — meaning one that is basically fit — in the sense of fit for living. There are several companion books, (and a companion poster). I don’t feel the need to buy the books, yet ;) but the poster might be handy.

§5 – Sleep

Published September 13, 2017  ·  All posts on Sep 13  ·  

This entry is part 5 of 13 in the series Changes and Results

Q: I’ve been entirely preoccupied by a most frightening experience of my own. A couple of hours ago, I realized that my body was no longer functioning properly. I felt weak, I could no longer stand. The life was oozing out of me, I lost consciousness.

Picard: You fell asleep.

sigh Sleep. Sweet. Rejuvenating. Blissful. …when you can get it.

Preamble

There is a huge amount of information about sleep available on the Internet. Over the years, I’ve collected a wide range of references upon which I’ve based my actions and opinions. I do this for a lot different topics, and I have a companion web site where I collect all the health related information I’ve found. In the case of Sleep, please see Sleep Quality, Light Sensitivity in the Human Brain, and Magnesium and Sleep over on Hilbert’s Library.

Darkness

I sleep best in complete darkness.

Long ago, I had no idea that light was messing up my sleep quality. Light is everywhere in modern life: it comes from windows, from doorways, from the alarm clock’s LED numerals, from the blinking LEDs on the WiFi router. But, after a lot of reading, and over ten years of experimenting, I’m convinced that light is enemy number one.

Sure there are other things which will wake me, (noise, movement, etc) but light is pervasive. Light is subtle. Light is insidious. Rage! Rage against the light!

So the goal for me is complete darkness.

Aside: Yes, I’ve considered using a sleep mask to cover my eyes. However, the human brain is broadly sensitive to light, so I’m not convinced a light mask is as good as a good old-fashioned dark room. See Light Sensitivity in the Human Brain.

My life is organized around the time on the clock, so I do not have the luxury of arranging my sleep around the sun’s rise and set. Therefore, I needed to manipulate my environment. When I began hacking my sleep at our apartment, my first light source to tackle was a street light that completely illuminated our bedroom through a high window in our cathedral ceiling. I had to buy a tall ladder just so I could climb up and cover the entire window with cardboard wrapped in velvet. Although we only had nearly-useless mini-blinds on all the other windows, this first light-reduction hack made an improvement in my sleep quality.

When we bought a house, the bedroom was the first room we remodeled. We set it up to be PITCH BLACK. The alarm clock is dimmed, there are no chargers or electronics in the room, and I added black-out curtains to the windows. Each night, when I first lie down to sleep, I cannot perceive a difference between having my eyes open or closed. (Of course, by the middle of the night, my dark adapted eyes can easily tell the difference.) If I step out of the bedroom in the wee hours of the night, the rest of the house seems so bright! There’s a light on the smoke detector, all the windows admit outside light, the microwave’s clock, the standby light on the TV, and on and on.

So my first suggestion is to get as close as you can to pitch black. Change things, move things, buy things, whatever — sleep is the most important part of your life.

The alarm clock

Initially, I had a generic alarm clock… beep beep beep BEEEEP! There’s nothing like waking up with a shot of adrenaline and cortisol to start me off on the wrong foot for the day.

First, I changed to an alarm clock which played music, but it had blindingly bright green numerals. Eventually I read about alarm clocks which have a bright light which slowly — over a half hour — fades up to fully illuminate the room. (Search for “Philips HF3470”; It’s discontinued, but it will get you going in the right direction.) Some mornings, the fact that “the sun has come up” in the room is enough to wake me up. But usually, the alarm clock proceeds to an audible alarm, and ours urges us by playing various tweeting bird sounds. (If I wasn’t so deaf, the light would probably wake me up enough to hear the actual birds outside.)

When to sleep

If you have all the above under control, you can technically sleep at any time of day. But there’s a catch: You need time to physiologically wind down before going to sleep. If it’s bright daylight when you want to sleep, you’ll need to craft a dimmed, calm space where you can relax and wind down. (But not where you actually sleep, don’t lay on the bed to wind down. More on not making your bed a multi-use space below.)

Consistency in sleep times is key. There are physiological processes which occur in the body which are not under conscious control. The body works on habit (and environmental cues) and it’s sluggish about changes. Wonky work shifts that make you change your sleeping patters are not healthy; if you’re into that type of work, just realize you’re trading your quality of life to accomplish your job. Be sure it’s worth it.

Remember: For me, sleep is the most important thing in my life. Work, play, scheduling, consistency… these are all things I’m will to work on, hack on, and change, to improve my sleep schedule because poor sleep leads to a poor life.

Temperature

Slightly cooler works for me (and agrees with what I’ve read.) But it doesn’t seem to matter too much. As long as you’re comfortable. But if the temperature is consistently UN-comfortable, you need to correct that.

There are obvious ways to hack the temperature, (e.g., air conditioning, a fan,) but you can also hack the general room environment. Figure out where the air moves through the room. (For example, if air normally moves from your open window to the door, move your bed to be near the window.) Get creative and sling a hammock across your room and sleep close to the floor, (where it’s cooler in summer, or closer to the ceiling where it’s warmer in winter.) Find the room with the best sleeping temperature and move your bedroom there.

Different mattress and sheet surfaces will feel cooler or warmer, so experiment to find what works best for you. Different types and extent of clothing obviously matters, but have you actually experimented to see how what you wear (or don’t wear) affects your perception of temperature?

Comfort

In general, splurge on things for your bed: Mattress, sheets, covers, comforters, pillows etc. Buy the most comfortable mattress, and the sheets you love to slide into. Then go another step and buy two sets of the sheets you love. (When you change the sheets you can strip and immediately remake the bed with clean linen.)

Improve the psychological comfort of your bed. Make changes, and build habits, which make the bed a comfortable, inherently relaxing, space. Room details such as color (hint: darker hues and blues are relaxing), lighting and general “busyness” of the room all have a subtle effect on your mood.

Slightly less obvious is to make your bed every morning. It doesn’t have to be fancy with specific folds or tucks, just make it up to whatever your definition of “made up” is. Later, each time you see the bed it will look inviting all made up, and you’ll look forward to peeling it open and sliding in.

Because it is a large, clear, open, space it will generally attract — but especially if you make it up each morning — random items throughout the day. Pay attention to what ends up on the bed and find proper homes, or invent systems, to keep those things off the bed. (For example: Clothes go ‘here’, worn-but-still-wearable items go ‘there’, pets are excluded by closing the door, put a chair in the room for sitting when dressing, etc.)

Avoidance

I’ve read various things about avoiding blue light in general, computer screens, TV, etc. But I’ve found that simply avoiding whatever it is that “winds me up” is sufficient to not sabotage my sleep. So, while I will look at my computer or phone near bed time, I don’t go to web sites or apps where I know I’ll get sucked down the rabbit hole. Instead, I’ll read through news feeds, e-books, or review my personal productivity systems and to-do lists. A lot of being able to readily fall asleep is related to my thinking-brain being relaxed. If there are things on my mind then I find I’ll be stuck laying awake in bed.

Eating

As with everything here, the key is to figure out what foods, and what eating times, affect your sleep.

I try to avoid eating within a few hours of going to sleep.
(In another part of this series, I’ll talk about intermittent fasting.) I find that I can sleep very well after a meal, particularly if I’ve had a couple hours for my digestion to get started.

What I’ve eaten also has a huge impact on my ability to fall asleep, and on my sleep quality. Too many sweets, or almost any amount of alcohol, to close to bed time will affect my sleep; I can fall asleep, but after an hour or so I find I’m wide awake. Same thing if I drink too much coffee. I’m pretty sure the stimulants (sugar, caffeine) and depressants (alcohol) affect my ability to reach the deeper sleep levels, and so I wake up instead of sleeping deeply. There’s a tremendous amount of information available about food and diet. Related to sleep, it’s worth looking into issues of digestion and experimenting to see what works for you.

Magnesium

There is solid evidence that Magnesium deficiency can cause sleep problems (restless legs, muscle cramps and more.) It is also a well-known relaxant. So that’s doubly suggestive that Magnesium (reading, experimentation, supplementation) could be very useful in improving your sleep. See Magnesium and Sleep.

Technology

There’s a lot you can do in terms of tracking sleep with things like Fitbits and Beddits. (Tracking is part of the “quantified self” movement.) Here again, the goal would be to measure something (sleep duration, quality, presence of sleep apnea, number of sleep cycles, etc.,) correlate that with how you feel and how it affects your life, and then make adjustments to your sleeping environment, habits and life in general. I did a small amount of tracking with a Fitbit. (I didn’t like the blindingly-bright green lights it uses for the pulse sensor. That’s how dark it is where I sleep.) But, for the period of time when I was tracking my sleep quality, it certainly helped focus my attention and efforts on improving my sleep.

Mental Activity

If I have too much on my mind, I sometimes have trouble falling asleep. When I first started working on my sleep I wasn’t yet journaling. Years later I started journaling and I found that emptying my brain in the evening was a wonderfully relaxing way to prepare for bed. Over the years, it became clear that as my time ran out each day, sitting down consistently to journal was difficult. So these days, I don’t regularly journal in the evening. (Instead, I write as part of my morning routine.) But sometimes I will journal to empty my thoughts if I feel that I’ve too much on my mind to readily fall asleep.

Room Usage

Don’t do anything other than sleep in your bed. Don’t read in bed, watch tv, or use digital devices. Whatever you do regularly, that is what you’re training yourself to do in that space. Have a “going to bed” routine, and turn out the lights.

Napping

For me, I can take a half hour blink-nap in the afternoon without it missing up my sleep. (A blink-nap is where I’m thinking, “I feel like I need a nap,” I lay down, blink, and a half hour has elapsed.)

Next up…

A few things I have not tried…

Andrew Foster: Global journey, losing everything, and finding purpose

What does it take to transform personal struggles and passions into a thriving community that fosters movement, connection, and belonging?

Andrew Foster shares his fascinating journey from his home-schooled beginnings in Ohio, Arabic studies, and living in Jordan, (including meeting and training with Danny Ilabaca in Cairo) to facing the dark challenge of losing everything- including his purpose in life. Starting renewed from his lowest point, on a mountaintop in Colorado, he describes finding new purpose and direction, bringing him full circle to his home town in Ohio.

We come from dust, and we return to dust. We don’t have anything except what we’re given.

~ Andrew Foster (16:09)

Andrew Foster recounts his life journey, beginning with a childhood filled with classical music, philosophy, and a homeschooling environment that prioritized learning over grades. He describes his forays into sports like swimming and soccer, where he embraced the challenges of being an underdog. His passion for movement led him to Parkour, despite initial parental opposition, and to formative experiences abroad in the Middle East, where he studied Arabic and connected with Parkour communities.

A pivotal moment came when Andrew faced personal and professional loss, culminating in a cathartic experience atop a Colorado mountain. This epiphany shifted his perspective on life, motivating him to embrace gratitude, faith, and a commitment to community. Returning to Ohio, he founded Akron Movement Family, a Parkour gym centered on movement, love, and family, with the goal of creating a supportive, inclusive space for individuals to thrive physically and emotionally.

Empathy Is a Clock That Ticks in the Consciousness of Another

Published September 8, 2017  ·  All posts on Sep 8

Yet whatever one calls it, we share a rough idea of what’s meant: a lasting sense of one’s self moving in a sea of selves, dependent yet alone; a sense, or perhaps a deep and common wish, that I somehow belongs to we, and that this we belongs to something even larger and less comprehensible; and the recurring thought, so easy to brush aside in the daily effort to cross the street safely and get through one’s to-do list, much less to confront the world’s true crises, that my time, our time, matters precisely because it ends.

§13 – On Noticing New Jumps

Published September 4, 2017  ·  All posts on Sep 4

This entry is part 25 of 37 in the series Study inspired by Pakour & Art du Déplacement by V. Thibault

I once visited the Hoover Dam in Nevada.

South of the dam, U.S. Highway 93 soars across the gorge 900 feet (270m) above the Colorado river. The view of the dam, from the pedestrian walkway on that bridge, is one previously seen only by helicopter. It is simply amazing.

There is a chest-high railing along that pedestrian walkway, and there is nothing above the railing.

The bridge is a “simple” arch span — all of the bridge structure is under the bridge deck — so there I was, standing on a sidewalk.

…next to a railing.

…900 feet in the air.

I leaned casually on that rock-solid railing and took in the unrivaled view.

I took some tourist-y photos.

The bridge occasionally quivered ever-so-slightly in response to a truck embedded in the streams of traffic flying between Arizona and Nevada.

I looked down, down, down to the river far below. It was a serene view; peaceful.

I noticed: The big, round, easy-to-hold top of the railing and the two-inch-wide concrete lip on the outside of the railing.

…and like a sucker-punch to the stomach, it occurred to me that I could turn-vault over that railing. I nearly threw up from the adrenaline spike. My knees went wobbly and had I not been on the sane side of that railing, I would absolutely have fallen off that bridge.

I slinked back to the car, hugging the side of the walkway away from the railing.

I have since looked up the numbers; it would have taken me 7.5 seconds to fall to the river, and I would have been traveling at 160mph (263km/hr) upon dipping my toes in the Colorado river.

I have never — before or since — been blind-sided so violently by a physical reaction. I went from calmly enjoying a spectacular view, to needing to immediately hurry the long distance to the end of the bridge where we had parked.

Noticing new jumps indeed.

Podcast Backstory

Published September 2, 2017  ·  All posts on Sep 2  ·  

Why doesn’t someone…

Hopefully, you’ve discovered the the podcast project. (Originally it was called “Parkour, They Said”.) The original project was entirely based on the written word and was inspired — ironically — by podcasts in general.

In late 2015, I was lying on the floor slow-roasting myself before the wood stove. I had stumbled onto a new-to-me podcast — yes I remember which one, no I’m not telling — and I was starting from their first episode. The episodes were horrible, but I knew they would get better, since a recent episode is what had drawn me in.

But listening to those early episodes left me with a litany of ideas:

I can’t even understand them with this crappy audio. Why aren’t all podcast episodes fully transcribed and available?

But honestly, no one would read the entire, long transcript of this horrible ramble-session. Why not break that large interview apart into its basic themes? Then people can read the entire interview, or just a part.

Why not have a standardized set of themes on the site? Then the “chunks” of the interview can be organized under those themes, and people can read just the material on a particular theme.

Why not add translation functionality? That’s way better than a podcast because people can read the interviews in many languages.

So wait, why bother with podcasts at all?

Why not just open it up with a form where anyone can write anything? Then people can contribute their writing in any source language, and the site then facilitates communication by translating everything to/from every language.

…and why not make it a generic project, conveying whatever everyone contributes? Well, what would we call that? It’s just a collection of whatever it is that people have to say…

“They Said”.

…and why not make several sites, each on a particular topic. How do we name and label each site?

“Parkour, They Said.”

(Bully on you for reading this far! You now know that the “Try Parkour they said, It’ll be fun they said,” meme is not in any way related to “Parkour, They Said”. :)

What could possibly go wrong?

I know, right… that whole project above is a TERRIBLE idea. (I’m not being sarcastic.) There are at least two, major problems:

  1. Writing is hard. People don’t like to write. Actually, it turns out that writing well is also very much harder. It’s as if one could make an entire living if one could write well. :P So this project’s success depends on… Oh, that’s a problem.
  2. The way the project works, and its purpose, are not the least bit obvious, and the name is downright obtuse. Worse, the name uses a wonky grammatical construct, (“topic, more information”) which is uncommon generally, and a straight-up Unicorn in spoken language. And the meme does not help. So, go ahead, say, “Parkour, They Said” out loud. Did you manage to convey everything about the project? Oh, that’s a problem.

But, whenever I spent 10 minutes blabbing about the project, people seemed to think it was a good idea. (This was probably the conversational equivalent of Beer Goggles on my part.) So, after many months of talking about it, we built it anyway.

“You should write something for Parkour, They Said!”

“Huh? What?”

I spent more than a year, randomly in my spare time, talking about the project and trying as politely as possible to repeatedly nag a few hundred people into writing. I learned at least two things:

  1. Writing is in fact really hard, and people already know this.
  2. “Parkour, They Said” is a strikingly unhelpful name for an already non-obvious project. If the project had been called Snorklewacker, (yes, yes it is, yes I did,) it wouldn’t have been any harder for me to explain, or any harder for everyone to remember. And just for the triple-bonus, start in the hole, difficulty score, we put it on a “.world” domain.

Surprisingly, a number of people actually managed to write some really interesting things. This made me very happy.

“Craig, why don’t you just make a podcast?”

I really like talking. (Everyone who knows me just laughed and thought, “collossal understatement there Craig.”)

Via a perfect storm of things not worth the deep dive, I wind up in a ton of fun, wide-ranging, interesting, and educating conversations. That’s not just me being hyperbolic; I regularly find people glommed onto my conversations. (I literally have a new friend who — their words — “was just eavesdropping the shit out of that conversation”, and we started talking when my original conversation partner moved on.)

People — often the people who were eavesdropping my conversations — started saying “that conversation should have been a podcast episode.” So the idea of making a podcast was gaining some footing in my head space.

But, I have a problem. It’s called shiny thing syndrome, or ADHD, or whatever. (“Get off my lawn! We didn’t have all these fancy acronyms back in my day.”) So I was really, REALLY, determined to not add “podcast” to my list of things to do. I already had this crazy “Parkour, They Said” web site sucking up time.

In one last-ditch, Herculean effort to avoid the inevitable, I started offering to help people write by recording Skype calls and passing them the transcripts. I think I did three recorded calls before I had convinced myself that-

oh! SHINY!

“Hello, I’m Craig Constantine…”

Finn Berggren: Gerlev Idrætshøjskole, sportification, and the Olympics

Published August 27, 2017  ·  All posts on Aug 27  ·  

Finn Berggren: Gerlev Idrætshøjskole, sportification, and the Olympics

What are the transformative possibilities of integrating Parkour into educational frameworks, and how can its values be preserved amidst sportification pressures?

Finn Berggren shares his thoughts on Parkour, explaining why he brought Parkour to Gerlev Idrætshøjskole in Denmark to replace the traditional gymnastics curriculum. We also discuss the “sportification” of Parkour and the Olympics, and he shares his story of the pivotal moment which solidified his decision to bring Parkour to Gerlev.

We built the first Parkour park in the world because it was a park designed to teach for pedagogical reasons and not just for doing, but also to learn how to do it and, at the same time, understand the philosophy behind Parkour.

~ Finn Berggren (7:00)

Finn Berggren shares his experiences as the principal of Gerlev Sports Academy, where he has transformed the institution’s approach to movement education by integrating Parkour. He recounts discovering Parkour through a television program and how its unstructured, innovative nature captivated him. His vision led to the creation of the world’s first pedagogical Parkour park, designed to teach movement and philosophy rather than competitive techniques. Finn discusses Gerlev’s evolution from a gymnastics-focused academy to a hub for diverse movement practices, including Parkour and street dance, emphasizing personal development and inclusivity.

Finn also reflects on the broader implications of sportification, warning against its potential to restrict the freedom and creativity inherent in Parkour. He advocates for preserving its unstructured, exploratory spirit and suggests using networks rather than rigid organizations to maintain its authenticity. Finn shares a personal story of witnessing children’s spontaneous engagement with movement, underscoring the importance of fun, challenge, and reflection in promoting physical activity and holistic development.

Takeaways

Fun as a foundation — Movement education thrives on enjoyment, which combats inactivity and encourages sustained engagement.

Challenges in Parkour — Emphasizes personal and mental challenges as vital components of growth.

Reflection in sport — Movement practices should promote reflection on societal and health impacts.

Parkour’s introduction at Gerlev — Brought new vitality and philosophy to the academy’s curriculum.

Development of the first Parkour park — A unique pedagogical space that merged practice and philosophy.

Sportification concerns — Over-structuring risks eroding the freedom and innovation central to Parkour.

Educational philosophy — Gerlev focuses on personal development over examinations, fostering individual responsibility.

Networking versus organizing — Networks are preferred to preserve Parkour’s values and resist rigid institutionalization.

5 willpower habits every man should develop

Published August 21, 2017  ·  All posts on Aug 21

To develop this trait favorably one should stick to a job until it is done. Form the habit of staying, not quitting. And when you do feel like quitting think of Joe who trained for the distances, or Daguerre who spent fourteen years to get a photographic image to stick on glass. Don’t be a putter-off.
