In some sports, being a lefthander might give you a substantive advantage over your opponents. In table tennis or in tennis, for example, lefthanders score better over their right-handed opponents. Why? Approximately 90 percent of professional table tennis players are right-handed. Therefore, a left-hander plays a right-hander in 9 out of 10 matches, whereas a right-handed player plays a leftie only in 1 out of 10 matches. Left-handed players therefore have 9 times more experience with such a match, and therefore score consistently better. | Photo: John McEnroe, one of the most famous and successful left-handed tennis players | Photo: <a href="https://commons.wikimedia.org/wiki/File:John_McEnroe_WTT.jpg?uselang=de">Wikipedia, Nrbelex</a>
