Come on...we all have some PlasticSpanner's post on 'Flashlights' made me think about this. So what totally useless facts do you have stored in your brain? Most of mine are about insects and animals. But I know so many, that it's hard to remember them all at once :mrgreen: Over the last couple of years I've compiled a massive list. No...I don't why? I just like useless knowledge. I'll just post a few to start with. A camel's milk doesn't curdle. Chewing gum has rubber as an ingredient. A cockroach can live up to a month, without its head. Elephants can't jump. When bats exit a cave they always turn left. A chameleon's tongue is twice as long as it's body.
