I'm not sure if I knew when I was young that how I treated my body then would determine how it functions now. I probably knew and just didn't take it seriously. I sure wish I had because I am paying big time now. I exercise a little bit every day and it helps a little but the fact is that I will die decades earlier than I would have if I'd looked after myself. And it's going to be painful. I've come to terms with it, I just wish I could help someone else avoid it but it's not really the kind of thing you can teach.
