In fencing (sword fighting), what makes left-handers successful?
Fencing is a sport where the very best practitioners don’t think, but react. This requires practice, practice, practice in order to develop an instinctual approach. The scarcity of left-handers means that right-handers don’t get a chance to practice (usually) and fail to develop that edge. Conversely, left-handers practice against right- handers frequently which give them more chances to develop a high skill level.
