One of the most important presidential traits is health, and our new leader replaces George Bush who was known for his physical fitness. At 47, Barack Obama is one of the youngest men in the Oval Office. An avid basketball player, he works out every day. Physicians describe him as fit and healthy, but the President has one vice -- he is a long-time smoker. He quit last year, but fell off the wagon a few times. His mother died of ovarian cancer and his grandfather of prostate cancer, but oncologists say yearly physicals catch cancer early. Michelle Obama, along with daughters Malia and Sasha, like to hula hoop. Hoop aficionados hope the popularity of hooping grows with the Obamas.
