(intense suspenseful music) - Water, what is it?

(water gurgles) Water, where is it?

(river rushes) Water, why is it?

(birds chirping) (dog slurping) Good evening, I'm Dr. Shermus T. Thermos, Esquire.

Welcome to "Inquiring Minds."

Did you know that water helps keep our bodies running cool?

When we exercise or run a fever, drinking cool water lowers our body temperature and keeps us healthy.

You can drink other things like coffee, tea, or juice, but drinking water is best because it doesn't have any sugar and it allows your mind to think more clearly.

Clear your mind.

Drink water.

Please do this.

I'm trying to get you to do this.

Drink more water.

So how did water get this monopoly on healthy human hydration?

And what do we really know about it?

Let's find out.

(dramatic music) Care to explain yourself?

(dramatic music) - It isn't alive.

It's just a pitcher of water.

(quirky music) - Well it seems this pitcher isn't today's guest at all, but simply a thirst-quenching refreshment for my real guest, who we failed to actually book.

Who was this mystery guest and what mysteries are they keeping hidden?

Find out next time on "Inquiring Minds."
