I'm somewhat obsessed with my brain, probably because my father died of Alzheimer's disease after suffering for years, and my mother ended her days not recognizing anyone. Tony Buzan's fun ways of keeping your mind working in Head First is very appealing to me--and obviously to millions of others. Without knowing how to Mind Map--something I want to talk about at some point--you can do some exercises to increase your "Verbal Intelligence." Buzan says, "Too many people feel that they cannot really improve their verbal skills--wrong! It is easy to become a Verbal Intelligence genius."
