Aged 29. Former football genius.
Rarely play anymore, fitness is terrible, hence reliving my glory days in the form of this message.
Nice thread chap!
Similar thing happened to me. It was around my late twenties that I started to do other sports MOST of the time, rather than football. Try playing 5-a-side if you can join a team. Your natural fitness should be still around, it just needs picking up off the floor and given a bit of a talking to. At 29, you could either turn to middle age quite quickly or extend your youth into your 40's. Don't turn to mush. I chose swimming and sailing, btw.
