You know, it's some genetics.

Okay.

You know, you cannot discount that.

I've been athletic my whole life.

So I started a routine, a habit of working out daily.

in my early teens.

It started with running, but I also started lifting weights in my teens.

I've always been competitive.

So the level of my athletics was, was such that I would be forced to dig deep and, you know, find the pain cave and all of the things they talk about right now.

I chose to be an endurance athlete.

So I chose to

first of all, I was a marathon runner in the seventies, quite a good one.

And from there, I got injured after seven years of, of overtraining and beating myself up doing that.

So I, I, I switched to triathlon.

And so my first triathlon ever was Ironman in Hawaii in 1981.

I went fourth in the 82 Hawaii Ironman.

So I've always somehow been associated with a type of workout that is basically managing discomfort.

You know, some people will play soccer and basketball or

I now play, you know, Frisbee, ultimate Frisbee.

But in those days, I was just managing discomfort every day.
