ALWAYS, after a non-fiction book goes to the printer, I find some fact or idea I wish I’d included. For 50 Underwear Questions, there were two: the radiation-blocking shorts and the Playtex seamstresses sewing space suits.

I hadn’t had any regrets for Seeing Red… until yesterday.

I was driving home from a play last night, listening to Q, and there it was. A random point from astrophysicist Neil deGrasse Tyson:

We have blood based on iron, and therefore red. If we had blood based on copper, as crustaceans do, it would be green. When we cut ourselves, we would see green. So, would green therefore be our warning colour, and would stop lights be green?

Who woulda thunk there could be a connection between streetlights and blood?! Yeesh… now I’m going to have to write a whole new book.
