We can put animals that exercise that don't exercise or eat something and eat an alternative option.

So the biology of the sense of purpose is not known, but we do know that people who have a sense of purpose, people who feel passionate about something, people who find that there's meaning in their life, is that they're far less likely to get Alzheimer's disease, up to 40% less likely to get Alzheimer's disease.

They have a 50% reduction in the strokes, 50%.

And it's not that the risk factors are the same, so when you compare people

in longitudinal studies, you correct for everything else.

There's a 50% reduction in strokes.

People who have sense of purpose have 50% fewer strokes than people who don't.

There's a 19% reduction in risk of heart attacks

people with sense of purpose live longer, have less stress, sleep better, enjoy life more.

The benefits of sense of purpose is just incredible.

We don't know exactly why and which neurotransmitter systems are activated.

There's some evidence that dopamine is activated when you feel that what you do today is in line with what you find meaningful.

I love talking about

prevention of Alzheimer's disease.

I do so many podcasts and I enjoy each one of them because to me,

It's great that let's say a thousand people who listen to your podcast decide, you know what, I'm going to change the way I look at aging.

And from today, I'm going to do this five pillars of brain health, and I'm going to set the goal that I'm going to reach the age of 90 and be sharp and independent.

I feel great that I contributed to a thousand lives.

Now, other person may have strong religious

drives.
