It's a very simplistic way to put it, but I think it's a fair way to think about it.

And that is part of the reason, if you look at, and I don't want to oversell this, but fasting, in a sense, is the oldest cure.

If you look at animals, if they get sick, what do they do?

At least mammals, most ungulates like deer and so on, they fast.

And if we get sick, we don't want to eat.

Your appetite's gone.

Yeah, but then we'll often force ourselves to eat, eating by the clock.

And I would say that the details do matter.

Like, that depletion of liver glycogen from at least the reading and research I've done seems to matter a lot.

So much like a ketogenic diet, if you do it halfway, you're actually not getting...

a lot of the benefits that the protocol seems to offer.

So I would say that's one.

I'll switch gears for a second.

I'm happy to come back to the intermittent fasting, but I would say in terms of beliefs and behaviors, I would say a focus on, just to really zoom out, focus on investing in, and I have very specific ways that I do this, relationships.

And the way that looks is if I do a past year review, as I'm doing right now, looking back on the past year, and I look through my calendar week by week and identify the energy-giving and energy-draining activities.

Where were the peak positive and where were the peak negative?

But also what types of things in my calendar drained me versus energized me?

And then creating a do more of column and a do less of column.

It's very easy to do it on a single piece of paper.

But the crux piece of that, that I ignored for a long time,
