Well, I definitely took up skiing later in life....I went into it seriously about 4 years ago at 54.....before that, I just did different things....mountain biking in summer, sometimes walking or running, swimming, scuba diving, I go to the gym regularly and lift weights. I've always done various different things at different times in my life and have never been a total slug about it. However, I feel I've been the MOST active during the last 5 or 6 years.....you have to take exercise seriously as you get older, you can't be sloppy about it or you WILL start to fall apart! I don't know anyone in my age group (personally) who is as active as I am, and consequently, most people I know around my age are looking and acting pretty shockingly old and out of shape. Their choice, I guess, but I'm determined not to get like that. I feel so GOOD when I'm regularly doing strenuous physical activity....I don't feel any different than when I was 30, and in fact, I'm probably in better shape now than I waas then! I LOVE to go skiing where I see people in their 60's, 70's, even older out there skiing and having great fun. I just saw Hans Obermeyer on a Warren Miller show....he's 85, and he was skiing and doing flips just like the boys.....totally inspirational.
