What it means to be mortal

We, like all living things, want to live on — we want to project ourselves into the future, we have this will to live. And yet, unlike other living things, we have to live in a knowledge that this will is going to be thwarted, that we’re going to die. And so we might have to live with this sense of personal apocalypse — the worst thing that could possibly happen, will. This is what it means to be mortal.
