I just wanted to thank you for the wonderful book "The Magic of Reality". I was surprised to find out it was initially meant for teenagers, because I'm 23 and I learned a lot from the book. I got very excited about the evolution chapter (My great grandfather is a fish!) and couldn't stop telling it to all my friends.
Also, I've stopped being quite so gullible about psychics, ghosts and all the supernatural stuff that I used to believe in... Now I think there probably is a better, more realistic explanation: the cold reading technique for psychics, etc.
