I tried to look it up but the internet doesn’t no

Hears my theory:

• people say “listen to your guts”

• guts has bacteria’s and are bacteria’s makes us happy or sad (this is science)

• guts are stinky because of the bacteria’s

• people say “follow your instinks”

So is that this is if why we say to follow your instinks because their are stinks inside are guts that tells us what to do?

What do you think?
