I've heard of him.

I say that right now, the tests that are done to measure biological age, and I did talk about this a little bit without going into detail, they're done on a population level.

So it's a very biostatistical test that's done that really, really relies on

large, large sample numbers.

And so there's these tests that are done.

They're measuring epigenetic changes, and they can basically measure your biological age.

But the standard of deviation is about four to five years.

So when you have hundreds of thousands of different people coming into that sample size, it's a lot more accurate.

You can actually do a large study and

and figure out like what someone's biological age is and what different lifestyle factors can regulate that.

When you go down to these consumer available tests at the individual level, it's a lot of noise because again, the standard of deviation is four to five years on average.

And so the test isn't really that accurate on the individual level.

So you could do that test and then do it again,

in two weeks and have five years difference, right?

So my take home from that is you can claim all these things being biologically 18.

I don't think that's accurate.

I think that Brian Johnson's doing a lot of things right with his diet and lifestyle and he is improving the way he ages.

It's a lot easier to reverse.

accelerated aging.

So in other words, if you were doing things bad in your diets, if you're eating a lot of ultra processed foods, if you're overweight, if you smoke, if you drink a lot, if you're sedentary and don't exercise, you're kind of accelerating the way you age.
