Is left-handed caused by brain damage?


Is left-handed caused by brain damage?

Being ambidextrous means you can use both of your hands with equal skill. Whether you’re writing, brushing your teeth, or throwing a ball, you can do it just as well with either hand. While many left-handed people also use their right hands pretty well, very few people are truly ambidextrous.

Is ambidextrous genetic?

What side of the brain is ambidextrous?
