I was watching Dara Torres compete with teen-agers an 20-somethings at the Olympic Trials in swimming. No doubt, swimming is a grueling sport but she keeps up with them.
Could a figure skater in their 40s conceivably keep up with teen phenoms and 20-somethings in competitive olympic or world figure skating competitions? Obviously, greater attention would need to be paid attention to rest periods, injury avoidance, nutrition, etc. But, could it be done?
