It becomes a problem because it, as I mentioned, leads directly to social isolation.

Which is a massive driver of long-term joy.

connection, purpose.

So all the physical attributes, sure, we can directly tie those to mortality.

We can also draw joy and sense of connection and purpose.

When you lose a sense of purpose, and in fact, you have a sense of burden, mortality is right off the reservation.

We've actually seen, we actually published a paper last year, and we found that specifically leg strength predicted 5% of cognitive function through aging.

And we have both correlation and causal data behind that.

And so it's examples of movement.

It's examples of physical activity.

You're not strong, you're not gonna be physically active.

sense of purpose, isolate.

So it ties into everything all the way up to directly brain functional purposes.

There's excellent research on strength training and white matter atrophy in your brain.

So your physical brain, not your mental health, your actual physical brain is going to stay around much longer when you strength train.

And again, there are direct causal links

at this point we can make the same argument for grip strength in fact one paper found um i know that this is a very large study they looked at grip strength and low grip strength predicted 30 percent of dimension alzheimer's wow so you pick the poison you want to go after

brain health, mental health, physical, you're going to find just, again, mountains of evidence to suggest strength training, the act of it itself, as well as just being strong, is going to be holding toe to how long and how well you live.

So you just can't make an argument that you can get away with being weak and living a long time.

I think maybe the problem is differentiating these things, these items, these approaches as performance-based.
