I have a friend who plays bridge. We tease him about this. Not too much, because I am all too aware that my complete collection of Frank Miller comics and Iain Banks novels is possibly opening me to charges of nerditude. Just possibly.

But after he showed me some of his rivals, I have come to believe that bridge has some kind of physical effect.

The world number one and Australia's number one, for example. But here's the thing: I bet I would enjoy hanging out with these guys. Up until they beat me at bridge, and I overturn the table in a blind rage.
