The advantages of being lefty Rafa Nadal, Maradona, Muhammad Ali... All of them have two things in common: they have been great at their respective sport disciplines and they are lefties (although Nadal is able to play with both hands). A new study performed by The Oldenburg University of Germany tells a good handle of the left hand may grant certain advantage in some sports. But, What sports in?. According to this study, lefties may get some advantage in very concrete sports where the time pressure play an important role, like tennis, cricket or beisball. Study's authors analyzed the Top-100 of the best players in several sports where time limitation played an essential role and exposed that the amount of lefties was of 30.4%. However, this amount was around of 8% of average in the rest of sport disciplines. But, Which is the cause of this advantage?. Some authors have suggested that lefties may have a more efficient brain connections. However, other researchers believe it all may be due to the surprise factor. That is, because of there are more righties than lefties, the first one are not so used to play against the second one. Caused by that, the time limitations would impede to righties having the margin enough for adapting to the opponent's game.
