The singlemindedness will end immediately

Michael Phelps will now start to discover whether an "eat, sleep, and swim" mentality is enough to sustain him a lifetime...

The question-and-answer session, arranged by one of Phelps’s sponsors, Visa, included journalists from The Harvard Lampoon, The Hollywood Reporter and a cheeky gentleman from New Zealand, a nonmedalist in swimming here, who, when called on, delivered a stand-up routine around the theme of Phelps’s greediness.

Phelps was asked to weigh in on whether light is a particle or a wave and describe love. His answer to both was, “I have no idea.”
