So having all these could allow you to do even more actually at the end than less.

And that's the exciting part of it.

So it's very simple as we've talked yesterday.

So imagine you're in the outside with no industrial light.

If your body thinks you're in early evening and you see a bright light, what does this tell you?

Oh, wait, this is not early evening yet.

It's still early afternoon or late afternoon.

So I have to delay my clock to go back to late afternoon.

So if you get light early in the evening, it delays your clock.

So what does- Meaning that makes you want to go to sleep later.

Yes, it delays your clock.

So later in the night, later in your night-

And actually, it just happens that in humans, you get a temperature in the deer later in the night, low temperature in your body.

After that, lights start advancing your clock.

Yeah, because then your body thinks, oh, it's seven o'clock, so it'll advance your clock by one to two hours.

Absolutely.

But you have to remember the light, right?

So let's, now that we explained it very simply, let's take a very simple example, right?

New York to Italy.

That's a simple example.
