So it's recommended that you try to stay in this 71-40, but it is a bit arbitrary, but it's not a bad rule of thumb to work by for the average person.

But again, some people have very, very good glucose control.

Some are moderate spikers and some are severe.

And it's pretty clear that excessive spiking, especially in diabetics, is associated with cardiovascular disease and other things.

There's some pretty strong papers out there on that.

So you do want to keep it under control.

And there's a very strong correlation between this time and range measurement I mentioned and something called hemoglobin A1C.

That's a measure of your steady-state glucose.

And so if you have...

High hemoglobin A1C, that's typically how we classify people for diabetes and prediabetes.

If you're over 6'5 or over, you're classified as diabetic.

If you're 5'7 to 6'4, you're prediabetic.

And if you're under that, you're so-called normal.

And this time and range will actually correlate very, very well with that.

So it's a surrogate measure for that.

But it's actually pretty cool because you can precisely see what's going on in real time.

Unlike a hemoglobin A1C measurement, which you get periodically.

So if you want to dig into that further, I would say that, you know, what's cool about these CGMs is that you wear them like I'm wearing one now.

You can wear them for about 14 days, depends on the particular device.

And you see exactly what foods do what to you.
