Do you ever watch The Amazing Race on CBS? Would you ever consider being on that show and racing?
Its a reality show where teams of two race against each other all around the world! They have to complete different challenges (like learn a Russian dance, jump out of airplanes, etc) that are relevant to the country they are in. Challenges can be physically or mentally hard.
I really enjoy watching the show but I'd never want to be on it. My husband on the other hand, would love to do something like that!
