Navel Power

In an odd scientific development, belly-button placement is being credited with sports success:

The navel is the center of gravity of the body, and given two runners or swimmers of the same height, one black and one white, "what matters is not total height but the position of the belly-button, or center of gravity," Duke University professor Andre Bejan, the lead author of the study, told AFP.

Who knew that navel-gazing could lead to sports science discoveries?

I suspect the reason that I'm so-so in a sprint
is simply excess belly button lint.
