It's not that they slow down.

It's like, hey, my best times are ahead.

So what does that do to your motivation?

It increases your motivation to keep running.

Yeah.

And I really, I would say in my life, one of the best examples of this is my mother-in-law, who's just a phenomenal can-do person.

I mean, she will literally, she doesn't believe there's anything she cannot do.

And it's, I love it.

And I love that my children see this as an example of, you know, in your seventies, you know, she basically,

I did the London Marathon, I think, in 2021.

And my wife, my kids, and my wife's parents came down to London to support.

And

My mother-in-law basically, I think, saw someone in their 70s doing it, and she literally came back and started joining her local 5k parkrun.

She thought, well, that person can do it, so can I. And then for a period of time, she was doing parkrun every week, which is 5k every Saturday.

So the whole idea that our beliefs have that much of an impact,

I think are absolutely massive.

This whole second power of beliefs, which is about anticipation, we can also, I guess, call it expectation, right?

That's right, yeah.

There was such a powerful example you shared about, I think was it Mr. A and the overdose.

So you just mentioned the placebo.
