It means mobility.

It means agility.

It means balance.

It means proprioception.

It means being able to respond to your environment.

I think to some degree, just playing a sport that has other people in it

is important because if someone's throwing a Frisbee and you need to react to that, you're training mitochondria in your brain that are able to energize the systems that provide your reaction time.

And I think cognitive exercise for your brain is things like working on your memory and on your creative synthesis and all those different aspects.

And I do think that a lot of people are thinking about this when they're 25.

They're like, I don't care if I can memorize a string of 25 numbers, but you're going to care if you can't remember anything when you're 75.

So I think that we really need a broad thought about this.

But by the way, do you know what athletes live the longest from the pros?

It's actually gymnasts and pole vaulters have have eight years on the general population and if you if you look at there's a study that came out earlier this year and It tallied up all of the pro sports players from all of the countries

who had the dates of their death published and who were notable enough to have had an article published about them.

And so they had many hundreds, I forgot the exact sample size, but they were able to statistically adjust the mortality rate to the general population from which the athlete came.

So if it was a Greek athlete, they were adjusted to the mortality rate of Greece when they died, like what you would expect after adjusting for location and age and so on.

And in the male athletes,

You had gymnasts and pole vaulters with eight years on the population.

And you've got cyclists, and of course you've got sumos, sumo wrestlers are 10 years below.

And you have a lot of sports that have high injury rates that are, especially a lot of stuff that has impacts to the hands, martial arts and things like that, where probably the sport itself
