I'm proud of Jonathan for the question. I only wish he'd been more direct.
When asked what he meant? He should have said, "Many people think the 21.34 WR was aided by performance enhancing drugs. In 1988, Flo came improved from 21.96 to 21.34 in the 200 and from 10.96 to 10.49 in the 100. She promptly retired the next year at just the age of 29 - the same year that out of competition drug testing was introduced the sport. Do you think that record was set by a clean woman?"
