Chew on this!

This is Richard Polt's explanation of Heidegger's thought on death:

What makes my life my own is ultimately the sheer fact that it is mine to live, mine to make something of, in the face of my possible non-existence. Every other possibility is something that I may be free not to do, and that someone else may be able to do just as well as I can. But my death is a possibility that necessarily faces me alone: no one can face it for me.

I think it's a very interesting thought.
