Humans have searched out fun for centuries - chariot races, dueling crickets, roller coasters, Rubik's Cubes. It seems we've always had a knack for finding interesting ways to have a good time. Of course, it wasn’t always that way. Our earliest ancestors had to worry more about survival than finding something to do in their free time.
