I think there must be something in the air in St. George because my hiking guides were 83 and 81 years young, and my tai chi instructor was also 84. I'm not sure how old my yoga instructor was because ladies don't give their ages away as easily but I know she was a grandma! Being with an older, healthy, vivacious crowd reminded me of the greatest goal of physical health, to be able to enjoy my life as long as I live it.
Some of these folks had been active all their lives, others only started when they retired, but as I talked to them the common thread was that being active was FUN for them! This wasn't on their "have-to-do" list but their "get-to-do" list. I think that's the secret. Good thing for me that I love yoga as much as ice cream!
I'm going to try to keep being active with the things that I love doing like yoga, hiking, and swimming, rather than get stuck in the idea that I "have to" run on a treadmill or lift weights (though I have found those can be fun too when you get in the mind-set to enjoy them).
Here's to a long-life worth living!
