Today is their day. The day of those who, in school, had to wriggle like an eel to avoid elbowing their right-handed deskmate. The ones who look at scissors with the same suspicion reserved for an alien object, convinced they were designed by a sadistic engineer. And what about the ballpoint pens chained to the post office counter? A small, daily reminder that they are on the “wrong” side of the world.
A Club for the 10%
Today, August 13th, is International Lefthanders Day. A minority, to be sure, but a tough one. Estimates say they make up about 10% of the world’s population. Not too exclusive a club, when you think about it, but enough to make them feel slightly out of sync their whole lives, like when you try to run while listening to a song with a limping beat. It’s a condition that we right-handers, immersed in a world made in our own image and likeness, struggle to even notice.
A Lefty’s Survival Guide
Growing up left-handed in a world designed for right-handers is a training ground for adaptation. They learn to use a can opener backward, to write in spiral notebooks by developing a handwriting that’s a mix of abstract art and a seismograph reading, and to pour water from a measuring cup by reading the numbers in a mirror image. Small challenges that have, perhaps, trained them to think differently. To find creative solutions. You just have to watch a left-handed friend tackle a can of tuna to understand that they’ve developed a kind of everyday genius, an art of making do that we right-handers can’t even imagine.
A Brain with Superpowers?
Because behind these small daily annoyances, a superpower might be hiding. Their brain, it seems, works a little differently. In left-handers, the right hemisphere is dominant—the one associated with intuition, creativity, and spatial perception. Some studies mention a more developed corpus callosum, the bridge of nerve fibers connecting the two hemispheres. This would translate into faster communication between the two parts of the brain. Basically, while a right-hander is busy searching for the right drawer in their mental filing cabinet, a lefty might have already opened a couple of pop-up windows with alternative solutions. Maybe they’re not all Leonardo da Vinci, but the idea is fascinating.
The Tactical Advantage
This different brain architecture finds its ultimate expression in sports. If you’re a runner, the difference might be minimal, although coordination is everything. But in situational sports, the one-on-one kind, being left-handed becomes a significant tactical advantage. The opponent, accustomed to facing right-handers 90% of the time, is thrown off. Their trajectories, their patterns, their automatic responses all go out the window.
Champions are Born (Left-Handed)
Think about it. In tennis, a lefty’s serve cuts across the court in an unexpected way. An unusual forehand forces movements one isn’t used to. It’s no coincidence that tennis history is full of legendary left-handers: from John McEnroe to Martina Navratilova, to that monster of strength and resilience who answers to the name of Rafael Nadal. And what about soccer? The greatest of all time, Diego Armando Maradona, caressed the ball with his left foot. Lionel Messi, his designated heir, does the same. And let’s not forget the world of motorsports: Valentino Rossi, “The Doctor,” is a lefty, as was the legendary and late Ayrton Senna.
The Power of Being Outside the Norm
Today we celebrate them, but it wasn’t always this way. For centuries, being left-handed was a stigma. The very word “sinister,” which in Latin simply meant the left side, became loaded with ominous meanings.
In the Middle Ages, and beyond, the left hand was associated with the devil, with witchcraft, with something to be corrected, to be hidden. Today, fortunately, that view is a thing of the past. Left-handers have become a living reminder of the richness of diversity.
They remind us that being outside the norm doesn’t mean being wrong, but possessing a unique perspective. And above all, they teach us a fundamental lesson: that the norm, the feeling of being in the majority, is by no means synonymous with being right. It’s just a matter of statistics.
