As I read about all youse old guys solutions to our aches and pains, I think about my back broken in a car accident in '85 (they wanted to fuse it and I said no, best decision ever) and my raggedy knees, twisted in HS football and street fighting. My solution is to build bikes where I sit back almost in a recumbent position. Many cruisers are built close to this, raising the seat keeps my knees from having to bend too far. Like most older guys (I'm 58) if I could lose the pudge around the middle I'd be better off. But I'm still in better shape then 95% of my classmates. 40th reunion this year, at the 35th I saw a bunch of old men and felt sorry for their wives, lol. We still ride on!
