My breathing has been stellar the [...]

In 1985, I was trim and fit (not to mention 20 years younger). I was walking every night, riding my bike at lunch, and I was down to 179.5 pounds. I am over six feet tall, and that was a good, good weight.
Let us fast-forward to 1999, about 14 years later. Somehow, [...]
I’ve written before about the cardinal rule of being instructed by a physical therapist or personal trainer, and it’s this: people are naturally efficient, and they are particularly good at exercising the muscles that they normally use, and at not exercising the muscles that they don’t normally use.

The connection with insulin and high blood sugar is concrete: “Type 2 diabetics have roughly twice [...]
