So that's kind of important, I think, as well.

They were middle-aged to older-aged adults.

And they tracked them over eight years.

So the follow-up period in this study was eight years on average.

And the important part of the study is how they measured their physical activity.

It was measured using these wearable devices, these wrist-worn accelerometers.

They wore it for a week at the baseline of the study.

And so then they took all their physical activity from that one week.

And then that was used to establish these physical activity levels for these individuals.

Kind of a limitation there.

Obviously, physical activity was only measured for a week using these accelerometers.

But, you know, as we'll maybe discuss later, it seems like a limitation.

But in a way, I almost feel like it's a strength because the strong association with these health outcomes almost assumes that this activity that they were doing during that one week may have been consistent over, you know, the next eight years or something like that.

Right.

And that was, I think, the major strength of this study.

So instead of self-report, which a lot of the previous studies for the guidelines did, this one was objective data.

And yes, it captured data.

It captured what physical activity they were doing, what exercise they were doing, I guess, so their structured workouts, but also, as you mentioned, just everything they did throughout the day.

This device was measuring every single activity in 10-second bursts throughout the day.

Every 10 seconds, it measured, you know, what is the intensity that their activity is, and
