CNN's Situation Room

Today at 6:50pm ET, I'll be on CNN's Situation Room to talk about left-handed presidents and their brains. It might be re-broadcast tomorrow at 6:50am ET and/or 8:55am. I free-associated a bit - let's hope nothing embarrassing emerges.

Update: In addition to left-handed presidents (Obama, Clinton, Reagan), it was mentioned to me that Osama bin Laden is also left-handed. Left-handers tend to be more variable than the general population. They are over-represented among the verbally gifted and are more likely to solve problems in unusual ways. But they are also more likely to be criminals. I guess bin Laden combines all three categories.
