I definitely agree; my idea of looking good is looking fit (I think I tried to say that before). And what lph said about looking good for one's age vs. looking younger is right on. I look good for 55. Do I look 40? I don't think so. I want to say to my friends who say they "can't do what I do" that this is what a fit 55 year looks like. Come see my cycling friends.
You know, Oakleaf, I think that I was a case of your thinking, but in reverse. I was always thin and then in my twenties, I gained about 25 pounds. I lost it and kept it off until I was in my mid forties (well I didn't gain as much). Both times, I was slow to accept the fact that I needed to do something, because I saw myself as a thin person. In fact the second time, I saw myself as a fit, thin person, even though I was barely going through the motions at the gym. The first time my husband took me out on the bike, I almost fainted. I still thought I was fit and thin until I was gasping for breath going up a teeny hill. Then I got pissed at myself and started on the right track to getting fit again.
That won't happen again.
