Your ___ is just a number

That could be said about your age or your weight. Come to think about it, it could also be said about the length of your hair, your height, the number of times you've churned butter while standing, or the count of teeth in your mouth that are really yours.
By 'really yours,' I refer to endogenous dentition that have erupted rather than the replacement parts that have been paid for by cash, card, or insurance.
I don't always engage in activities or behaviors that seem age appropriate. For example, at 63 I have hippie hair. The hair is naturally wavy and the waves are not in synch with one another. So when the hair is brushed or combed, there is always a certain amount of tension against the teeth of the grooming device. The only time the hair flows like silk is when I have just emerged from my morning ablutions and the hair has been treated with some 99¢ Only Store hair conditioner. Then I look in the mirror and say, "Marcia, Marcia, Marcia!"
I'm also quite aware that I have a diagnosis of pre-diabetic. Not sure how long that has been around or how long the HgbA1C values have been used as DM metrics, but they are in place and they are not to be ignored. The question that one bids is, "What's a boy to do?"
Why, the answer is simple : "DIET and EXERCISE!"
At 63--with a predisposition against and abhorrence of breaking into a sweat--the notion of exercise is not even a theoretical possibility. So I ambulate. It has some effect... it just doesn't move mountains.
This is a fascinating subject (to me) and I am certain I will revisit it
