Only 10 percent of the human population prefers using their left hand over their right. On one hand, the science suggests that being born ambidextrous may come with slight disadvantages, not only for cognitive functioning, but also for mental health. The cause could be down to the way the seasons affect the hormones. This is one that simultaneously manages exploration and exploitation.

So if you’re ever teased for being a lefty, remind yourself that they have a higher chance of developing those painful conditions. Seeing as only 10% of the human population is left-handed, and that the remaining 90% of right-handers have created a world that basically outcasts us lefties, we deserve our own day. There are countless struggles that come from being left-handed, but also a multitude of pros. Typically there is only about a 10% difference between speed and accuracy with the dominant and non-dominant hand. Remember that the brain is cross-wired to the body. But being ambidextrous is certainly a good skill to have. When tested, people are found to associate things on their right-hand-side with being good and things on their left with being…not quite right. Researchers believe it’s related to the underlying DNA that creates left-handedness––the genes that are associated with lefties. In fact, humans are the only species on the planet that show handedness. It probably doesn’t have to do with your handedness, though. Still, I love being different.” Having to overcome obstacles, and always challenging yourself, ultimately makes you a stronger person. Such claims have been popular for more than a century.

And so, to the question of how learning to use one’s non-dominant hand might affect brain function, there is no easy answer. However, a conflicting study of more than 1,000 people debunked the myth that “right-brained” people are more creative than “left-brained” people. According to a classic study, researchers observed that left-handed people showed a lower rate of error in a spatial orientation test than righties. It was initially thought that a single gene controlled handedness, however recent studies suggest that multiple genes, perhaps up to 40, contribute to this trait. What does this mean? Spatial skills will always be important (yes, even in the age of the GPS)––you never know when you and your right-handed counterparts will get lost in the woods and you’ll be able to save the day.

As it turns out, left-handers are shown to have better self-control than right-handers. Some people are heavily handed: they do everything with their right, or their left, hand. He is also the author of the book “Making Habits, Breaking Habits” (Da Capo, 2003) and several ebooks: → Dr Dean’s bio, Twitter, Facebook and how to contact him. The cognitive functions are spread out in the brains of lefties, which means that in theory, when you have a stroke (which is typically concentrated to a small area of the brain), less of your cognitive functioning will be affected. All of you right-handers may be thinking, "Why do THEY get their own day?" Each of these genes likely has a weak effect by itself, but together they play a significant role in establishing hand preference. The vast majority of us favour the right hand, and most of the rest prefer the left. You should also try out one of these quirky inventions made for lefties.

Jackson and his followers believed that the brain’s hemispheres are distinct and independent, and that the preponderance of right-handedness was effectively wasting half of our potential to learn. Left-brained people also have their speech and language centres in the left-hand-side of their brains. No spam, ever. the concept of being able to disprove good scientific ideas by data is called falsifiability ___is the process by which scientists with expertise in the a particular field assess a study before it is published in a top quality scientific journal Don’t miss these other myths about lefties that we all need to stop believing.
