I spent most of this past weekend in a classroom taking a continuing education course on balance. It was an excellent course, and very applicable for me as I happen to see quite a few geriatric patients. At any rate, the instructor showed us a video at one point. I found it on YouTube and thought I'd share it here. The next time a patient tells me they're too old to do something, I'll show them this woman. Now, she starts off rather sedately, but things really pick up at about the two minute mark, so watch the whole thing.
A little research revealed she was only in her 70's when this was filmed, not in her 90's as some suggested.
