My doctor was flabbergasted. Since I can't think of any other change in my life style, we both concluded attending the university did the trick. So for lowering cholesterol, the fashionable curse of the aging, I recommend all doctors take note and send their patients to a writing course or something similar they'd really enjoy. Celia's Cholesterol Control. Incidentally, driving to classes doesn't work.
Patients have to take the bus and to make sure a good deal of walking is involved, too.
The trouble with me is that I'm an admirer of Mark Twain's ideas on exercise. I have found a brisk walk of about 30 minutes at least 3 times per week does wonders, mentally as well as physically. I get following the walks. Then I don't feel quite as guilty when I gorge myself with non-fat frozen yogurt as a reward. By the way, mall strolling does not count, though I suppose it is better than sitting.
