Because one of the hallmarks of aging is a reduction in the capacity to metabolize and buffer glucose.

And so as glucose levels become less and less regulated, all sorts of bad things happen.

Bad things happen to microvessels in the body.

So if you think of the most extreme example of this is type 2 diabetes.

So once a person has type 2 diabetes, what are they at risk for?

They're at the risk of reduced vision and ultimately blindness.

amputations of their digits, impotence, right?

The penis has tons of tiny blood vessels in it.

And the more that, you know, glycosylated proteins accumulate there, the less they get blood flow and obviously damage to the small blood vessels of the brain as well.

So all of these things are hugely problematic when glucose is dysregulated.

And again, the most important thing that you can do to regulate glucose, in addition to the obvious, which is eating in energy balance, not eating too much, is making sure you have large insulin-sensitive muscles, which means large muscles in the context of an individual who's sleeping well and exercising

And you're going to basically have a great place to put all of that glucose when you consume it.

Again, it all depends on the total energy balance.

But yes, it's clearly going to make a difference, right?

So one of the surest ways to reduce your capacity to store fat is to add more muscle.

Meaning you did one of the grip meters or you did a hanging test?

Yeah.

Grip strength, of all the strength metrics, it's one of the most highly correlated with longevity.

We actually prefer to do it like a 10 squared where your colleagues tested yesterday.

We prefer to do it on a dead hang.
