Midlife crisis

I've been quite surprised by the effect turning 33 has had on me. I'm feeling suddenly a bit limited. I know it isn't old, but I'm feeling a bit old all the same. Not in an aged body way, but in a "I'll never ski at the winter Olympics" way.

Naturally the best way around this crisis is to scheme up some new ideas. The one I'm toying with at the moment is to do the New York Marathon. It basically appeals because I want to go to New York, and will probably be flagged because I don't even want to run a local marathon, so why the hell would I do one there?
