And I have my phone and automation on my phone that turns it totally red at 8 p.m.

So I just got super serious about my circadian rhythm.

And my energy overall has just never been... I was doing it to try to get rid of these migraines, but I've never felt as energetic.

I thought napping was normal a lot of days.

don't nap, don't use an alarm clock, more energy, better mood, more patient.

So it forced me, it was really difficult.

Like it really impaired my work for a while.

It impaired everything.

Your relationships, everything.

Everything, everything.

But it did force me to get fanatical about my circadian rhythm.

And I now wish I had just done that years ago, separate from this.

Wow.

That's interesting.

I mean, what are these mnemonic, what is this?

Mnemonic devices.

It's like memory techniques where you relate something to something else that helps you remember it.

So the simplest ones would be things like an acronym, right?

But in cases of the numbers, this guy in the study, he was a runner.

And so he would relate it.
