"Every now and then, someone will tell me that one of my books has made them laugh out loud. I never ..." — Mary Roach

I've always been a bit of a space geek. I wrote an article years ago about the neutral buoyancy tank, which is this biblically sized pool where they train astronauts. And it was just the coolest thing.

Weightlessness was unbelievable. It's physical euphoria: Nothing about you has any weight. You don't realize that you are weighed down all the time by yourself, and your organs, and your head. Your arms weigh down your shoulders. In space simulation, you get to fly like Superman! You're hanging in the air! It's the coolest thing.

Pet foods come in a variety of flavors because that's what humans like, and we assume our pets like what we like. We're wrong.

I don't read good books anymore, it seems; I just buy them and put them on the shelf and every now and then walk over and pet them. I'm like the optimistic dieter who fills her closet with clothes two sizes too small and dreams of the day she can wear them. I know just what I want to do when I retire.
