Most of you are familiar with a sliding scale. This is often associated with the fee charged being in proportion to your income or current means of paying for it. Sarcopenia is the proven concept of losing muscle mass as we age as a part of the natural process. The fact that it happens to a degree is a given. How much it happens is not. Sarcopenia is also a sliding scale. As antidotal evidence I talk about a atory of an 80 year old New York man who runs a crossfit gym out of his back yard. Not only does he run it, but he leads people half his age by example.
