Your brain washes itself at nighttime. There's been studies where they've watched people when they're going to sleep, and they've seen pulses of cerebrospinal fluid going over the brain during sleep. They really think that this maintenance time of sleep helps remove bad things for your brain, toxin buildup.

Well, the why do we age is certainly a question with an answer. You know, there's very deep-rooted ways that our cells and the cells of all living things work that makes them age. And one of the main things, as, you know, anybody who works on aging will understand, is that our DNA, the code that makes us what we are and are the instructions for us being alive, has a lifespan in and of itself.

So, you know, every high school student knows that DNA gets copied. But what they don't realise is every time it gets copied, that copy is only a tiny fraction smaller than the original. And eventually it's too small and it just goes away, you know. So that in itself is a limit. It's a ticking clock and there's nothing we can do about it.

So, yeah, that's a bit of a problem for people who want to live forever, I'm afraid.

Well, it's a maximum clock. So most people don't reach that. That isn't the sort of critical factor in what ends up, you know, finishing us off, essentially. So we'll all get old and we'll all age. But there are other factors that will damage our cells, damage our DNA. You know, exposure to sunlight makes our skin look older.

the other lifestyle choices what we eat you know what we do how much exercise we take how happy we are how stressed we are so it can even be a case of you can sort of think yourself young and that is literally going to be physiologically true because stress responses age our cells and aged cells go into a state called senescence which is effectively where they shut down and start to die off and that's contagious other cells around it can pick it up

And the stress response is a big factor in senescence. So if you're a very stressed out person with a bad lifestyle, you're gonna age a lot quicker than someone who's just happy-go-lucky and looks after themselves. So you can maximize your chances of being younger for longer, but not forever.
