McCain's wisdom paradox

Chuck Norris says McCain may be too old for the presidency. But aging has some upsides for mental functioning as well as downsides, and the downsides are reduced in people who maintain an active lifestyle (a presidential campaign certainly qualifies). I recommend anyone concerned about the age issue and McCain, or just about the age issue period, read The Wisdom Paradox: How Your Mind Can Grow Stronger As Your Brain Grows Older.

My review of the book for Scientific American Mind is reprinted (minus paragraph breaks) on the book's Amazon page.
