In short, it makes your gut contract

This was a delightful video, absolutely enjoyed it.

Oh so that is why I have to poop ever since I started drinking coffee!

Rats are brilliant animal model for biological studies relating to humans due to significant similarities to us. I will say though seeing a result in a single study on rats doesn’t mean “definitive this is how it works in humans” and think the video should have concluded in a less “and that’s the answer” way.

Cool video, just iffy conclusion.
