It's a new workday. Have you heard about Brian Johnson who says he wants to live forever? He says he's

47 years old. He looks good. He says he's got a body of an 18-year-old when he does his tests. Do you follow what he talks about, Brian Johnson? I don't know. Maybe you've not heard of him. I've heard of him. Okay. He's our age. I think he's a year older than us. And his claims are his entire idea is anti-aging I think he wants to

live forever and he sets his body's an 18-year-old body what do you say about that 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 ages 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 they're that,
