But he said something else that was really key that maybe we can kind of transport onto the exercise piece, because you can probably sense where this is going, is he said, and every five years update that number.

And I was like, really?

He's like, yeah, every five years.

He said, you know, you're in your 20s now.

Back then I was in my 20s.

He said, you could probably work 15 hours a day, which I probably did.

I probably at that time I was a little maniacal.

I probably worked 15 hours a day, five or six days a week.

In graduate school, that number actually went up.

But then I noticed I started getting sick a bit in when I was a postdoc.

So I had to throttle back.

And so I wonder if we could kind of transport that onto the exercise thing, which is – because we've got people listening now that are probably in their teens, 20s, 30s, 40s, 50s, 60s, men and women, different goals, sort of like what can I do every week –

for the next five years, assuming you don't get injured, no major life crisis.

I feel like that's kind of the way I approach this.

And it turns out for me, it's just been three days a week of resistance training, two or three days a week of cardio, one full day off.

And likewise with my work, I adjust every five years or so.

And I'm wondering what your thoughts on, I take no credit for this.

This is all Bob Knight, MD, PhD, but I thought, wow, like this simple thing is such a gem for me because back then I thought,

I just need to work as much as possible.

But he understood eventually you'll hit a wall.
