But I like to be human.

I like my sleep.

Sleep should be what physical activity is already for many people.

It's an essential pillar of health, and we should value it.

But we shouldn't obsess about the messages on your wearable that tells you, oh, you didn't get any deep sleep.

First of all, that data is probably not something you can rely on.

And also, one night of bad sleep isn't the end of the world.
