Went to H.E.B. yesterday morning for free blood pressure and blood glucose tests. BP of 110 over 87 73 was no surprise. But the BG of 91 was. A happy achievement. My annual physical, a month ago, had it pegged at 126, the threshold of diabetes. The difference was a month of largely eschewing sweets, excessive fats and carbs, and walking a mile almost every morning.
I can eat the old favs, just not every day, and not very much when I do. And the exercise, which I largely avoided in youth, has become mandatory. All potentially depressing, if not for a conscious effort to introduce more variety into meals and activity than I ever thought about doing when young. Old habits turn potentially deadly as one’s meter reading climbs. Old dogs can’t learn new tricks? On the contrary. Them as can’t might as well get back in bed and turn their face to the wall. It’s over.
UPDATE: I heard the title from a friend. I didn’t know, until recently, that it was a paraphrase of one of SciFi author Larry Niven’s "Niven’s Laws." Just wanted to set the record straight.
THE TEXAS SCRIBBLER 
I get dragged out about twice a week for a (let me do a quick calculation) about three miles forced march. That an Lipitor once in two days seem to have me balanced so far. Oh well…
Yes, my gp tried to get me on a generic version of Lipitor, until I got him to admit (based on Google searches) that my cholesterol was merely marginal and not that high. But the walking definitely helps keep it that way.
When I was in my forties, I would exercise in spurts, like in the months before July 1988 when I planned to attend the 125th anniversary of the battle of Gettysburg and wanted to hike all over the battlefield. When it was over, I went back to being basically sedentary. Can’t do that anymore. Alas.
