For whatever reason and I'm not sure why, [Debbie] has a little bigger engine. Put it in friendly terms, Amy has a 2-liter and Debbie has a 2.8-liter engine. As a physiologist, I wonder why. The size of muscles is the same, height is the same, and weight is the same. They both have guts. Both want to win. Both try hard. Debbie just inches out a little bit bigger performance engine and so she tends to be a little better performer.
