Pediatric?

That was my hesitation when the first time someone offered me melatonin is from doing this podcast and speaking to smart people like yourself, I've come to learn this sort of principle that if you start making something for your body in terms of a hormone, if you start sort of consuming something externally,

like testosterone, your body will say, fine, I don't need to do this.

It will try and return to that level of balance where the quantities in your system are maintained, which means it kind of learns to shut down.

And I always think about the case of testosterone, because men know that if we start injecting testosterone, then we're going to have to pretty much do it forever.

Yeah.

If we want those levels to be the same.

There's always a trade-off.

And some of my friends often like talk to me about like these miracle things or this thing or take modafinil and everything will be fine.

And I go, yeah, but what's the trade-off?

And I get most concerned when they say there isn't one.

Because then I go, shit, we don't know it.

Lots of you.

I grab my phone before my eyes are even open.

Okay, so that's the third pillar.

Regularity.

Okay.

And then I have the T for timing.

Which we'll go through these.

Quantity, which we've talked a little bit about already, and quality.
