Now, there are ways to actually measure your fitness and then monitor it

objectively, but you can also just do it by your own measures that you're one notch better every six months, that you can do a little bit more every six months.

I must add that there are parts of the world where people are more active than they used to be.

Many high-income Western European countries have seen a drop in the incidence of Alzheimer's disease in places like Denmark, Norway, Sweden.

where people are active on a regular basis, you've seen a drop of 20% in the incidence of Alzheimer's disease in the past 20 years.

I was in Amsterdam for the Alzheimer's conference two years ago, and I love that these older,

people they clearly looked like they're in 80s were biking and their bikes had little basket in front and the grandchildren like two or three grandchildren were sitting in front of the bike and here was this older grandpa who was biking through the city and i'm not surprised that they have a lower incidence of alzheimer's disease because these people are being more active

And as a result of not only activity, but interacting with the grandchildren, many of them eat right, many of them do the things that those five pillars of brain health is a drop.

One study in Framingham showed that the incidence of Alzheimer's disease in Framingham area has also dropped by 13% in the past 20 years.

So in places where people are doing these five pillars of brain health, especially with more activity, we are seeing a drop.

It's not...

not everything is doom and gloom.

And this is like a live experiment in countries where people are just doing it.

They're not necessarily have signed up for a 12-week program.

They have learned that these good habits are good for them and are doing it.

You know, I was doing a triathlon

a couple of years ago and I was so proud of myself.

I had done like a mile and a half of swimming in the ocean and I've done like 26 miles of biking.

I was doing 10 miles of running.

I was toward the end feeling good about myself.
