In fact, I would argue that you should have two alarm clocks.

You should have a to bed alarm clock and to wake alarm clock.

Most of us only use an alarm clock in the morning.

Why don't we have it to tell us when it's time to go to bed?

So I have both of those.

So I would say that it's good to use to keep yourself regular, but truly if you would sleep past that alarm time, then you're probably not, you're not done with sleep.

Your body isn't done with sleep and animals would not, would never do that.

And so I think that's the first metric.

Another metric, sometimes it's not that incredibly specific, but have you ever been driving day after day after day?

And sometimes you think, I don't know if that light was red or green that I just went through.

I'm actually driving, Matt.

Bite your tongue, Walker.

Bite your tongue.

So that was you.

May have been.

That's one potential concern.

In fact, one of the ways that we've developed a metric for...

dose response to sleep deprivation is using concentration and alertness tests.

So in other words, if there is a breathalyzer for a lack of sleep, doing these concentration, focused concentration tests is, they are so sensitive, they're so predictive.

And- It just becomes monotonous.
