True, but I also think a lot of it is lifestyle, and to a degree, access to activity/economics. I've recently become reacquainted with several people I grew up with. None of them are overweight. In fact, they all look great. Every single one of them either goes to the gym almost daily, and/or runs, rides, or swims outdoors. Since we are all turning 60 this year, it's interesting. In fact, more of the guys looks overweight and "old." I can give a more detailed report in June, when we are having a 60th birthday celebration for everyone. I am going to get to see some people I haven't seen since 1969, when I moved away. My observation is based on Facebook pictures, and seeing people at the 40th reunion, 2 years ago.
