View Full Version : Righties vs Lefties and the science behind it

I tore my AC joint in my should two weeks ago and had to use my left hand for everything. At first most things (like shaving) took forever but after a couple of days my dexterity got surprising better. It got me thinking, I wonder how people become right/left handed. I wonder if I could ever get as good at tennis playing lefty as I can play righty.

I also wonder if they'll be more Rafa Nadal types (natural right hander but taught to play lefty) because being a lefty is advantageous in sports like tennis and especially baseball.

Anyone know the science behind it?

there isnt really any science. everything a lefty can do to a righty, a righty can do to a lefty. its just that lefties are used to playing righties and thats where they have the advantage. its familiarity more than anything else.

Lefties use the opposite side of the brain, but anything can be learned with enough time. I'm not actually ambidextrous, but I can do more things with my left hand than most righties can do. I can shoot with either hand when I play basketball, I can hit groundstrokes with either hand in tennis, and I can use a fork and knife with either combination of hands. Most of these things came more naturally to me right handed, but after doing them lefty for a while, it didn't feel so unnatural.
