Miss Marple has pointed out several times that Kerry doesn't seem to engage in competitive games. Only biking, skiing, etc, where he doesn't have to "score" against someone. I was reading Golf Digest this week, and apparentely Kerry used to golf quite a bit more than he has in the past few years. He had a handicap at a club up to about 3 years ago, but they only listed about 2 times that he had played golf in the last 2 years.
ouch!
That'll scar a guy.
