I didn't know my true self until this very conversation.

I'm Angela Duckworth.

I'm Stephen Dubner.

And you're listening to no stupid questions.

Today on the show, we have cow milk and goat milk.

Why not take milk?

They're smart, skittish, suspicious, and paranoid.

It sounds like a good description of a University Chicago economist.

Also, what's a food that seems gross to most people, but you find delicious?

I think a lot of the foods I like are discussing to many people.

Stephen, we have an email that is about a really interesting question.

I'm going to read it to you.

Please.

Hi, guys.

This might in parallel your no stupid questions theory, but why don't humans drink pig milk

or consume pig milk products?

Is that too stupid a question?

The email goes on.

Camels, cows, goats, yak, mousse, sheep, buffalo, reindeer, wherever a sizeable mammal has been

domesticated for food, it seems that some group of humans has incorporated its dairy into

their diet.

Why not pigs?
