For example, I think that's a non-intrusive way.

I think the mattress may be as if not better because it's a completely frictionless device.

You don't have to remember to charge it.

You don't have to put it on.

You just fall into bed and it tracks your sleep.

So I, one form factor I like to think about sleep trackers is, is the form factor itself, but then the other is accuracy.

And I think right now, if you look at the data, probably aura is winning the ring kind of wars.

You know, if you look at all wristband wars, I think it's probably the most accurate relative to something like, you know, Fitbit or Apple watch or the whoop band, but they're all, you know, pretty close, but I think aura

I think Aura is probably the leader in class right now, at least.

Keep in mind that I used to be an advisor for Aura.

I want to make that very clear.

So take what I say with a grain of salt in that regard.

I think to your question, well, I'll come back to mattresses in just one second.

For people who are struggling with sleep, I think you've got to be very, very careful with sleep trackers.

because they can have the counterproductive effect where I gave you the example of alcohol or eating too late, and these sleep trackers help you modify your behaviors to improve your sleep.

Well, there are places where these trackers can actually do you a disservice.

When you get so hyper-focused on your data and your data not looking good each and every day, it becomes a self-fulfilling prophecy of a negative spiral.

And we now have a condition in sleep medicine called orthosomnia.

So ortho in medicine typically means straightened.

So you've heard of orthodontics, straightening teeth, orthopedics, straightening bones.
