And this study was published in the British Journal of Sports Medicine.

Okay, so let's break down what this was all about.

So this all starts, like I said, with this biobank, right?

Researchers mined this huge database to find study-appropriate study subjects.

So in a lot of ways, this is like a database archaeology than anything else because this has already existed before.

with lots of information so that it really didn't even, all they did was mine that data and then evaluate the data is ultimately what they did.

So with a half a million people in there, as you might imagine, there was a lot of winnowing, there was a lot of filtering out.

So of those half a million people, 100,000 wore motion sensors on their wrists

for seven consecutive days back when they were added to the database years ago.

So they wore the motion sensor, and that is actually kind of a big deal, wearing a motion sensor to determine activity, because a lot of studies like this, they use self-reporting, right?

And that is steep, you will agree.

Notoriously overestimations.

People are horrible at relating, like, how active are you?

How much time do you spend working out?

All this stuff.

So having something that's much more objective, having the sensor on their wrist for seven days, I like that fact, that it didn't rely on self-reporting so much like so many other similar studies.

So there's that.

So that was a critical thing that they were looking for.

They wanted these people.
