The "use it or lose it" hypothesis is well-known, but the newest approach adds the "active grandparent" to the equation.
The idea of “use it or lose it” can perhaps be traced to the pioneering work of sex researchers Masters and Johnson who concluded that, for women at least, having an “interested and interesting” sex partner was the key to battling the effects of aging onfunctioning. From a broader perspective, the concept of remaining active to benefit physical if not cognitive functioning has continued to receive extensive support.
Unpacking this novel idea, what might strike you right away is the proposal that grandparents aren’t just some sort of evolutionary accident, the result of medical and social improvements that allow people to live by their “sell-by date” when they no longer can reproduce.
Citing a wide range of data to support their position, the Harvard research team conclude that if PA didn’t stimulate repair and maintenance of physiological functions, it would “shorten, not extend, healthspans.” If you’re thinking “no pain, no gain,” you’ve got the basic idea.
