I have a friend who can only snap with her left hand.
Like, why?
Why is that?
Nobody knows.
Some people don't always golf or bowl or shoot a gun like we said to match the hand they write with.
It goes back to what you said about the eyes because it's not just handedness.
We have dominant eyes.
feet, sides we chew on, which nostril we're breathing out of.
And they don't always favor the same side, right?
It's not random chaos.
It's evolution's way of saying, hey, let's specialize here.
Yeah, I mean, we think so.
I mean, there's definitely some things in lefty fine print.
It's very early on in the research.
But left handed people tend to hit puberty later than their peers.
There was a study that showed left handed boys reached puberty about a year later than their right handed peers.
More studies are needed on this, though.
That's because you're left handed.
There's another weird biological fact.
And this isn't just a left handed phenomenon.
