So that is something I think that's really interesting to follow.

But in general, I think from a public health perspective, this could save health systems hundreds of billions long term.

And we ought to be taking it much more seriously and integrating it into holistic and educational advice.

Yeah, I've been impressed by some of the science coming out of this and the fact that I quite enjoy it, just actually enjoy it from a hedonistic point of view.

So I try and have a sauna twice a week if I can do that regularly.

ideally with a cold plunge afterwards, but the science isn't sure whether that makes a big difference.

It's like just a workout for your blood vessels in your body and your brain.

So I think that the science is quite compelling and yeah, it makes me feel good, which is always, should be part of anyone's health routine.

Something you enjoy doing is always easy.

Yeah.

If you look at the happiest long-lived populations on the planet, they've all got really good social lives.

They are always dining with friends, going out.

Often that does involve a little bit of alcohol in most of these societies.

but that doesn't seem to adversely affect them.

The idea of having a key group of core friends you see regularly, I think is really good for your mental and brain health.

And loneliness has got to be one of the worst things for your brain health.

So really important to maintain your good friends.

I think we haven't talked about early life experiences and stress.

What, trauma?

Yeah, so one thing... And we haven't talked about talk therapies and conventional treatments.
