What Are The Benefits Of Being Left-Handed?

Being a lefty myself, I’m always keen to read and watch more about the reasons why humans aren’t split down the middle when it comes to hand dominance. Turns out science doesn’t have a specific answer yet, but that doesn’t mean we can’t hear what the popular theories are and explanations as to how our brains, animals and even the universe, has its preferences for right and left.

This post was originally published on Gizmodo Australia.

It’s Okay To Be Smarts Joe Hanson, who previously explored the practicality of interstellar melee, this week takes on the topic of left-handedness.

As mentioned, there’s no solid answers just yet, but it is fascinating to learn about how the different centres of our brains — language, for example — can be located on either hemisphere and how certain genes can do a good job of predicting hand dominance… though not entirely.

Having two left-handed parents boosts the chances of having a left-handed child to 29 per cent, while a right-handed couple is just nine per cent.

The world may be out to get us with its scissors and, uh, pens, but at least we can become professional tennis and baseball players (or marauding Vikings) knowing we have an advantage.
