Since vitamin D is cheap and readily available, we don't need to wait before making sure we have enough of it.

Grip strength is another proxy for health, specifically how likely you were to die anytime soon. Makes sense. But training your grip won't make you live longer.

Still taking the vitamin D tho...

Have you actually done (or read) a study to show that grip training doesn't increase lifespan?

I think one would look for a mechanism for how that could work. "How could grip training increase lifespan?"

I can't think of a mechanism for that effect, where something else wouldn't be probably better way to spend that effort. Like cardio training.

"Hypertension markedly increases the risk of cardiovascular diseases and overall mortality. Lifestyle modifications, such as increased levels of physical activity, are recommended as the first line of anti-hypertensive treatment. A recent systematic review showed that isometric handgrip (IHG) training was superior to traditional endurance and strength training in lowering resting systolic blood pressure (SBP)"

That is WILD. Thanks!

Are you saying that we can correlate general health to vitamin D levels?

Yes there is some correlation. People who are generally healthy tend to spend more time out in the sun.

Given enough data we can correlate pretty much anything to anything
