She missed out on qualifying in 2008, but used the disappointment to her advantage. "At the time, missing the Olympic team was one of the hardest moments I had faced.

She also battles a secondary condition that sometimes causes her heart to stop at random. She is forced to carry a defibrillator with her in case of emergencies but remains calm about the situation and hasn't let it affect her swimming. "It happened a lot when I was running," she said. "So I don't run a lot. I basically said I would rather die swimming than not do it at all." (NBC Olympics, 09 Jul 2004; The Washington Post, 09 Aug 2004)
