Gatorade Scientist?

What medical qualifications do you need to be a "Gatorade Scientist"?

Every year, I watch the World Junior Hockey Championships. Every year, they run Gatorade commercials -- featuring teenagers who are prohibited from being paid for their valuable commercial contribution -- that feature "Gatorade Scientists", talking about the importance of hydration.

Water is better. Noooooooooo, Gatorade is better. Water sucks, it really really sucks. Tackling fuel.
