What If The 'Fountain of Youth' Is ... Sleep?

#254: Sleep As A Step Back In Time
...................
Previously, in my series on sleeping:
* Timing: my system
* Exertion: staying asleep
Now:
* Sleep: The elusive 'fountain of youth'?

It was just this year that new research showed deep sleep clears the brain of toxins associated with Alzheimer's.  Which suggests that developed sleeping skills enable us to, each night, rewind the clock.  Failing to do so, the study points out, is cumulative, in that the uncleared brain gets less deep sleep, which means less clearing in the future.

So, perhaps, a 'natural' human life-span is 100-200 years, and it's only the befuddlement of sleep deprivation that shortens that span by half.

If so, it might be a good idea to teach sleep fundamentals in school.  Like the frankly amazing results from teaching 'character', a periodic reminder of sleep 'hacks' every month or so in a student's PE class might bear fruit.
