My father did it when he was a child so he could "be like his brother" who was 1.5 year older and the favorite son of his mother (this brother was the first male son after a female who was the first overall).
He is now right handed for almost everything but really skilled with the left hand, I remember that once he broke the right wrist and could easily write with the left hand for example.
