That's right.

It's stunning, isn't it?

And you can almost see it, if you have a partner and they come through to the sort of kitchen in the morning

they look at you and because you're so familiar with that face, because it's a face that has imprinted on you thousands of times, you can notice subtle changes and you can sometimes sense, they do look tired, but you're absolutely right.

You don't say that, you just say,

You know, how are you this morning?

And is there anything I can do for you?

Should I make you a coffee?

Maybe you should go back to sleep.

Yeah, yeah.

I think that's the politically incorrect, indirect way of saying, boy, do you look tired.

Two things on that front.

The first, it comes back to the immune system.

That sort of

pale parlor in a face almost that sickly looking skin in part is because you're already seeing the effects of the immune system and it's the same with the bags under the eyes that part of this reboot of the human being you know that human beings seem to have what i would describe as a recycle rate and it seems to be about 16 hours that after about 16 hours of wakefulness

we need about an eight hour-ish, and it's seven to nine hours is the recommendation.

Don't get hung up on eight, and we'll speak about exactly that in a second.

But that seems to be required to reset this whole panoply of health and physiology of a human being.

One of the things is the immune system, and you get this sickly look about individuals, and you get the bags under the eyes.

So that in part explains it.
