There seems to be some interesting similarities between Michael Phelps and Missy Franklin. For one thing, they are both over six feet tall. Next, both swimmers have a shoe size of either size thirteen or fourteen. Moreover, both have long legs and long arms. And there fingers and body fat are a certain ratio as well. Therefore, could it be these particular body characteristics that give them an advantage in the sport of swimming? If so, shouldn't America be putting more people of this type into swimming so that more medals are won?
