Yeah, that's right. So let's actually use the word energy. As you know, in the cell, there is a physical power plant called the mitochondrion, which is supplying us with ATP, which is the coin of the realm for the cell to be able to operate all of its machinery, right? And so one of the things that happens when you get older is that your mitochondrial run down.

That's right. They're less efficient. And actually, drugs can do that to you, too. They can harm mitochondria.

No, the drugs you take for illness. I'm not sure about recreational drugs, but I know it's the case that there are a lot of drugs that people take because they have to. But... But the other thing, and this is something, that's the bad news. Here's the good news. The good news is that you can replenish your energy by exercise. Exercise is the best drug you could ever take.

It's the cheapest drug you could ever take that can help every organ in your body. It helps obviously your heart. It helps your brain. It rejuvenates your brain. It helps your immune system. Every single organ system in the body benefits from a regular exercise. I run on the beach every day.

They are, they are. And so this is something, this is something that has kept me active and it's, and I do hiking. I went hiking in the Alps this, in last fall. So this is in September. So this is, I think, something that people really ought to realize is that it's like putting away reserves of energy for when you get older. The more you put away, the better off you are. Here's something else.

Okay, now this is jumping now to Alzheimer's. So a study that was done in China many, many years ago, when I first came to La Jolla, San Diego, I heard this from the head of the Alzheimer's program. He had done a study in China on onset. And they went and they had three populations. They had peasants who had almost no education.

Then they had another group that had high school education, and then people who were, you know, advanced education. So it turns out that the onset of Alzheimer's was earlier for the people who had no education. And it was the latest for the people who had the most education. Now, this is interesting, isn't it? And presumably the genes aren't that different, right? I mean, they're all Chinese.
