BBW, Cyclists are going to be people more concerned with their health than most, I was a jogger until my knees start to complain excessively and hung out with the same type of people. Personally I started a little later in life and enjoy bacon-egg-cheese biscuits too much to be a serious dietican. But being concerned and having probably abused their body a little with bumping into thunderbolts and crashing into trees they are now trying to figure how to live well as long as possible. Not really weird, you are approaching the twilight zone (senior citizenhood). Hang out with younger people, just don't follow them down that trail your crashed on 15 years ago.
