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

I'm Cody Goff. And I'm Ashley Hamer.

Today you learn about how brushing your teeth can slow aging with help from author Andrew Steele and why dolphin and whale blowholes start

out as regular old noses. We'll also answer a listener question about what happens when humans

manipulate the weather.

Let's satisfy some curiosity.

Yesterday Andrew Steele told us about the exciting approaches scientists are taking to slow

aging and keep us healthy for longer.

Go back and listen to yesterday's episode if you haven't heard it.

Now in that conversation, he mentioned a few ways we can stave off aging ourselves while we wait for those treatments,

stuff like exercise, healthy eating, and brushing our teeth.

Yeah, believe it or not, poor dental health is linked to diseases of aging, and Andrew Seal is going to explain why.

He's a computational biologist and science writer and author of Aegeless, the new science of getting older without getting old.

Here he is with some obvious and not so obvious advice on how to slow the aging process.

I found that health advice falls into basically two

categories and the first category is things that sound kind of obvious but

actually understanding the aging biology behind them makes them a lot more

compelling. I think a really great example of this is exercise. aging biology you realize it's literally slowing down the aging process.

It's affecting your whole body in ways that are, as I say, effectively as they are aging more slowly.

That's really encouraged me, you know, I wasn't a couch potato before,

but I'm really trying to make sure, you know,

I do get my half hour, you know, go running
