Well, it's possible to be mentally ill and rational.
I want to make something, and I want people to know I made it.
I have a form of ESP that allows me to consistently pick losing lottery numbers, and generally make poor life choices.
I'd rather die terrified than live forever.
When I played doctor I played to win.
And when our sun explodes and we are all destroyed, we'll be rocks and chunks of I am not sure what, and maybe we'll rain down on somewhere else.
