Hugh Jackman, Bill Gates, Julia's Child, Gordon Ramsay, Da Vinci.

It's a really long list and the rates are higher than in the general public.

Yeah, already happened.

20 percent of U.S.

presidents have been left handed, including Obama and Clinton.

A high percentage of politicians through the ages have been lefties, much higher than the general population.

Julius Caesar and Napoleon were left handed.

Yeah, I mean, that tracks Tina Fey, Cardi B, Chuck Norris, all lefties.

Yeah.

And we can celebrate this rare trait every August 13th, which is left handed day.

Yeah.

Whoever sets these kind of things suggests everyone try using their left hand as much as possible that day.

I'm on it.

And it's fun to see how long you can try and use your less dominant hand for things because it's such second nature.

It's just you forget, you know, it's just who we are.

Yeah, I think so, too.

But it just comes down to a chance of so many different variables.

We think that most instances of left-handedness occur simply due to random variation during development of the embryonic brain without specific genetic or environmental influences.

But we will understand it more and more as we continue to decode our genes.

You know, there's just no doubt handedness is complex.
