Why Are Some Of Us Left-Handed? | BYJU’S Fun Facts

We all know that humans tend to have a dominant hand. That is, the hand we use to do most of our tasks. About 90%of the world’s population is made up of right handed people. Only 9% of the world’s population is made of left handed people. And so, left handed people end up being the minority in the right handed world. This has a lot to do with the brain and its left hemisphere and right hemisphere. While research suggests that being a left handed person might have something to do with genetics, it is not yet proven. It is fascinating to think about why some people are left-handed. Is there a difference in how the hemispheres of the brain works for left-handed people?

In this video, we answer all these questions and more. After all, there’s a reason why we celebrate international left handers day!

My Brother is also a left handed... My parents never pressured him to use his right hand... Now he is a great artist as well as his handwriting is also so great...

[allrounders]

The remaining 1 percent are known as ambidextrous . Ambidextrous is they use both the hands as their dominant hand .I came to know this while watching Cricket . I love seeing Cricket, where I see that some cricketers use right hand for bowling and left for batting and vice versa. Fun fact : even I use left hand for bowling and right hand for batting just to be cool 😅

Remaining 1% of the population are called "Ambidextrous" which is very rare. People who can write with both of their hands and use both of their hands equally. They don't have a dominant hand like others, they make use of both hands equally.
And by the way, the video was awesome. A clear information about left handers...I really liked the way you explained mam... I'm a left hander too😃🙂

[veenasingh]

I had a question, there was a boy in our class who got fractured his right hand now as a write hander he could not write with left one but after some practice he started to use his left hand now even when his write hand plaster got down he used to prefer his left hand and became left handed. So my question is that why he did not became ambidextrous.
