As it is Wimbledon I thought I might research some tongue in cheek epidemiology. According to Wikipedia about 10% of us are left handed and wanted to compare the number of left handers who have won the singles vs right handers.
There have been 19 different winners since the open era of 1968 and one would expect 1 to 2 left handed winners, giving us an OR of 1.9. However these people are left handers Rob Laver, Jimmy Connors, John McEnroe, Goran Ivanisevic, Rafael Nadal, making 5.
So we can conclude that to be a Wimbledon champion, being left handed increases your chances by 250%.
Come on Rollo trash my work 🙂
