Useless Trivia

Perhaps not entirely useless, depending on how your mind works....

1) A squash ball moving at 150 kilometers per hour has the same impact of a .22 bullet. It's wonder more squash players aren't killed.

2) During the female orgasm, endorphins are released, which are powerful painkillers. So headaches are in fact a bad excuse not to have sex. But then, you already knew that sex was a very good thing.

3) Astronauts get taller when they are in space. I'm assuming this is zero-gravity by product, a different gravity pull presents so many interesting opportunities.

Please add your own bits of fact or fancy...I love trivia.
