Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Discovery.

Time flies when you're learning super cool stuff. I'm Nate.

And I'm Callie. If you're dropping in for the first time,

welcome to curiosity where we aim to blow your mind by helping you to grow your mind.

If you're a loyal listener, welcome back. Today you'll learn about a new test that can

show how well each of your organs are aging.

Some interesting links between comfort food and stress and a surprising finding about

certain snails.

Without further I do, let's satisfy some curiosity.

Over the past decade or so, there's been a lot of talk about the difference between

chronological age and biological age.

Right, I mean, chronological age is literally how old you are according to the date you were born, and biological age is a little trickier.

As I understand it, isn't it basically kind of a measure of how well your physical body is aging?

That's exactly right.

So you could be, say, 35 years old, but because you exercise a bunch and eat a healthy diet,

the wear and tear of your body is that of, say 28 year old and that tends to be a better measure of your

potential lifespan right that is the idea but of course it's not always super easy to

calculate your actual biological age but a new method developed by researchers at Stanford aims to give an accurate assessment,

not of your total biological age, but the aging rate of 11 different major parts of your body and that could be a huge deal.

Okay wait a second what does that mean exactly? Well it's potentially a really

incredible test so it turns out that one thing that makes determining our biological age so difficult

is that our different parts don't all age the same way. For example, someone might have the heart
