And I said, wait a minute, we have to fix that.

And this was 20 years ago.

They went and they got a hearing aid and he felt much better.

He started participating in conversations and he started doing things, skiing, fixing things around the house and everything is gone.

Perfectly.

Crazy.

And this was 20 years ago.

And he is now in his eighties, looking great, no memory loss.

So there's simple thing, vision loss, hearing loss, air pollution.

You know, people who live in dense areas with air pollution, the air pollution can affect the brain functions.

there are so many little things that can affect brain function.

And unfortunately, unfortunately, people jump on the A word.

When you have hearing loss or vision loss or these other things, you don't participate in conversations as much.

You're withdrawn.

And those two factors, the fact that you don't challenge your brain and you have withdrawn, you feel isolated, those two factors can literally shrink the brain.

Because you don't stimulate the brain and because you're lonely, those factors shrink this part of the brain I told you about, the hippocampus.

Hippocampus is the size of your thumb.

You have one on the right, one on the left.

And this is ground zero for learning and memory.

And it needs to be stimulated in order to function well.
