i bought beer for the first time 2 months ago and my knees hurt when i ride fixed too far. Although 7 years of pole vaulting will take a toll on the plant leg. I had to sell the fixie but hopefully will get another one not too far from now. I am a mtb kid for now though. This thread is pretty inspiring though, I would love to be riding any kind of bikes when I am as old as some of you cryptic ones. Keep it up!
