Because they couldn't get around this non-negotiable thing called sleep. Yeah. And so I think for me, what that really tells us is that If sleep doesn't serve an absolutely vital set of functions, it was probably the biggest mistake the evolutionary process ever made. And now we realize it didn't make a spectacular blunder. It is- We need a cleanup. It's cleanup.

Sleep is mother nature's best effort yet at immortality based on everything that I've seen.

I mean, if you look at the data, there has been a pernicious erosion of sleep time over the past 100 years. Now, if you look at it over the past 10 years, that creep has maybe not been so demonstrable. But really, think about it. We evolved over millions and millions of years for our evolution.

And it's taken mother nature millions of years to put this necessity of a seven to nine hour sleep need in place. And then within the space of a hundred years, we've gone from something that seems to be based on the data around about 8.4 hours of sleep a night that we used to be getting a hundred years ago.

Now, if you look at the data on average, Americans are sleeping about six hours and 40 minutes. Now don't forget, That's the average. That means that there's a good proportion of people who sit to the left side of that distribution, who are getting even less than that. America is not the worst culprit, by the way, Japan, we're all at each other's throats and not thinking clearly.

We think about that and we giggle about it. But I don't think it's a factor to be discounted in our emotional dysfunction. Your empathy, for example, we did a great study and we were looking at how empathetically sensitive a human being is. And boy, do you just simply start to ignore other people's pain and their needs. No, you feel like crap, so it's hard to care, right?

You feel so bad yourself. Why? Because you've got to take care of... You know that your brain... Well, let me put it this way. Human beings are the only species that will deliberately deprive themselves of sleep for no apparent good reason. Like doctors, you mean? Like doctors, exactly. But what does that tell us? That tells us is that mother nature has never had to face
