If you're under-predicting, say, oh, see, it's not happening, so they have to goose the numbers down.

Now they're pretending like they were under-predicting.

All right.

Thanks, Jay.

All right, Bob, tell me, how many minutes should I be exercising every week?

I think if the question is, are we doing enough?

The answer is no.

I want to define enough.

I know what the standard definition of moderate activity is.

It's enough to get your heart rate up, but you could still talk while you're doing it.

Oh, okay.

That's a good way to... Severe, rigorous exercises like you're too out of breath to talk significantly.

But overall, it sounds like this is good news.

It basically just means that there isn't as much of a ceiling on the benefit of regular exercise as we thought there was.

So you could do even better.

So just do as much as you can.

If you could do more, there's more benefit to it.

But we do have to emphasize the caveat that this is an observational correlational research.

Yeah, that's what I'm saying.

That minimum is like, yeah, if you do the 150 minutes a week, that's kind of where the benefits start.
