All those systems basically were born out of heart math, the wearables.

Our research, we popularized heart rate variability biofeedback back in the early 90s when this research was published.

In fact, Dr. Donald Singer was on our advisory board and he coined the term heart rate variability.

He's also since deceased.

He

All these other systems for recovery and how HRV can be measured as a number worn at the list, and you see a number and you want to increase your number, are measuring the amount of HRV, which is really important.

So when I go these rolling hills, the amount is how high is the hill and how low does it go?

Because we want that to be a lot.

That is

reflects resilience and recovery.

And we have the most of it when we're little kids, when we're babies, because we're very emotionally resilient.

And then we lose it naturally as we go older, we get more emotionally habituated, more rigid, less flexible.

This can keep you supple.

It's great for the whole longevity anti-aging movement because you want to be emotionally youthful.

And that's where coherence practice helps.

But we're not measuring amount because you can't do that co-pattern from the wrist.

The wrist drops the interbeat interval so you don't get to see the heart rate change beat to beat to beat to beat and how that reflects your motions.

That's why we have a sensor like this that connects to your ear, that connects to the app.

Or we have a sensor in the HeartMath app that you can at least get an idea with a sensor from the camera lens.

You put your finger there and it reflects.
