It's a humid summer evening in Gainesville, Florida, in 1965.

37-year-old Dr. Robert Cade plops down on the living room sofa in his modest ranch house,

exhausted. His wife, Mary, puts a hand on his shoulder as Cade takes off his thick glasses.

The breeze from their rotary fan cools his overheated face.

How was work, Bob? Well, Mary, I'll be honest, it

wasn't great. After work, the fellas and I stopped by the thirsty gator for a pine or two just to

talk about it. When Cade says the fellas, he means his research team. Kate is a world-renowned

nephrologist, that's a kidney specialist at the University of Florida.

And for weeks, he and his researchers have been working on a special assignment.

Players on the university's football team, the Florida Gators, have been collapsing on the field

from dehydration. The football stadium is built on swamp land, and the extreme humidity

makes an 80-degree day feel unbearable, even before the tackling drills start.

But Kate and the team think they found a solution, as in a literal solution, a drink that will replenish the salts and fluids athletes lose when they sweat.

Nothing like this exists on the market.

It's a real breakthrough for science and for sports.

Or at least, Cade had thought so until he tasted it.

Oh, Mary, you wouldn't believe how awful it was.

Now, Bob, how bad could it be?

Well, let me put it this way. As soon as I tried it, I threw up.

So that's not good.

Oh, no, probably not.

For Dr. K, this setback is worse than just a queasy stomach.
