From the brains behind brains on, this is the moment of um.

Answering those questions that make you go,

Um, um, um, um, um, um, um, moment of, comes to you from APM studios. I'm Rosie DuPont.

Um.

Sometimes it's kind of hard for me to fall asleep. I'll hop into bed, turn off the lights, and my brain just spins and spins.

I'll try laying on my back.

I'll try falling asleep on my side, on my stomach back to my back, and on, and on, and on.

Nothing works.

But you know what I haven't tried yet?

Upside down.

I mean, it works for bats.

I wonder why, though.

Hi, my name is Kiara, and my question is, why do bats sleep upside down?

So why do bats sleep upside down?

That's a great question.

There's so many things about bats that are really, really cool.

Hello, this is Deanne Reader. I'm a professor of biology at Buckdowne University, and I study bats. They're the only mammals that can really

fly, and so their hands have become wings, and their fingers have gotten really long.

And their legs have turned backwards.

And there's all kinds of interesting different ways in which their bodies have adapted to be able to fly.

But it means that they're really not very good at standing up.

And so bats tend to roost or hang upside down almost all of the time.
