Yet if you don't understand the physiology of a biological system or process-like female sexual arousal-you can't possibly come up with a way to fix it when things go wrong. No one would have come up with a treatment for diabetes if physiologists hadn't figured out how metabolism, blood sugar, and insulin work.

To me, NASA is kind of the magical kingdom. I was sort of a geek, and you go there, and there are just these wondrously strange things and people.

The way I see it, being dead is not terribly far off from being on a cruise ship. Most of your time is spent lying on your back. The brain has shut down. The flesh begins to soften. Nothing much new happens, and nothing is expected of you.

In my whole life, I've never vomited from seeing something disgusting. Does it really even happen, outside of movies and TV? I believe it may be a myth.

Life contains these things: leakage and wickage and discharge, pus and snot and slime and gleet. We are biology. We are reminded of this at the beginning and the end, at birth and at death. In between we do what we can to forget.

I dont fear death so much as I fear its prologues: loneliness, decrepitude, pain, debilitation, depression, senility. After a few years of those, I imagine death presents like a holiday at the beach.
