The series kicks off with a look at the changing size and shape of the Average American. When our country was born, America was the tallest country in the world, and we held onto that title until the 1950s. Today, we've plummeted to number nine in the world rankings. But we are, however, distinguishing ourselves in a different way: in the past 100 years, America's average waistline grew from a size 26 to a size 34...and we are now among the fattest people in the world. When and why did we stop getting taller and start getting wider.
