Today, in a heavily jetlagged frame of mind, I fired the game up again. 68. Oh well.
Actually, I've just been thinking, if the better you are at the game the younger your brain age is, the best way to win is to set there going "Goo Goo" and sucking a dummy.
Note : this is not the case. According to the book, your optimum brain age is 20. I'm going to head for 12.
