Hello, smarty listeners. Please take a moment and leave us a five-star Apple rating review.

It not only helps us grow the show, but we might also read your review on Who Smarted.

So do it now. And don't forget, you can listen to Who Smarted anywhere, including Apple podcasts,

Spotify, and Amazon Music, including hands-free listening powered by Alexa on all Apple, Android,

and Echo devices. Hey, smarty pants, think about the last thing you ate. How long ago did you

gobble it down? Five minutes, half hour, over an hour ago? Well, you must be starving.

Here's another question for you. When do you think you'll be seeing whatever it is you ate last

again? In other words, how long does it take food to pass through you?

And what's that journey like? Because whether it's a chicken nugget, a toaster strutal, or a grape,

anything you eat takes a long and winding and strange trip through your digestive system,

where it undergoes a series of amazing processes and intense changes.

But what exactly happens inside you after you take a bite of something? To find out, I've recruited

two experts. But it would be boring to just have them tell us the answers. Instead, they've agreed

to shrink themselves down and enter my digestive system. Unfortunately, we couldn't afford a fancy

interspaceship for them to travel in, so instead, they're just going to hitch a ride on this Oreo

cookie that I'm about to eat. Before we begin, I just need them to sign this waiver so they can't

sue me in the unlikely event they get stuck inside my intestines or they're accidentally digested.

Just initial here, here and here. Perfect. Now, let's meet our experts, Dr. Martha and Dr. Ron.

Hello. This is very exciting. I'll say, Martha and Ron are both what is known as gastroenterologists.

Which means they specialize in studying and treating disorders of the digestive system.

Ah, hopefully there's nothing wrong inside of me and this is a nice, smooth ride.

Well, an apple might be smoother than an Oreo. Yeah, but an Oreo is more delicious.
