Death is something we think about... birth is something we don't. The question of what death is like is very similar to the question of what it was like before we were born. We simply... are not.
I don't want my death to be in vain. So I figure if I ever find out I have a terminal disease and nobody knows about it, I would pick a really good cause to protest, make a big sign, call the newspapers and reporters, and cover myself in gas buddhist-monk-style and burn myself in protest!
But I guess I'd have to go to great lenths to make sure I wasn't played off by the media as crazy
