What It Means If You're Born Left-Handed or Right Handed

It's not a matter of preference...

Growing up, we were told that deciding whether we wrote with our left or right hand was down to what felt right.

However, it turns out that the decision is made before we're even born.

Despite the decision coming down to genes, there seems still to be some bias, as an overwhelming 90% of people are right-handed. However, the reason for more people being right-handed is not entirely known. 

As children grow older, they then show signs of favouring one or other hand as they begin to draw and write more.
