No, I was blessed with thin parents, so I am thin, no matter what I eat, or how often.
I often wonder if I had a sedentary job, if I would gain weight. When my wife complains about gaining a few pounds, I tell her to follow me around for a few days, and do what I do. I don't think weight gain would be an issue.
I am starting to feel the aches and pains of old age though, if that makes you feel better.
