This isn't to say every left-handed person suffers from bad allergies, but if you're a lefty and tend to get a runny nose or itchy eyes, then this may be connected to those modified microtubules.

It's currently being researched.

Another inexplicable health effect is that left-handed people are more likely to drink more often.

So the research on this is really limited, but there have been some studies showing a significant correlation between left-handers and an increase in alcohol consumption.

This isn't to say that left-handers will become full-blown alcoholics or

but on average, they do tend to drink more.

Maybe.

A lot of this is correlation, though, not causation.

But another thing seen in higher rates in lefties is that they report more vivid dreams.

I don't know, but it seems from what I've read, it's probably because their brains won't stop multitasking in both hemispheres.

But studies indicate left handed individuals are better able to recall having vivid dreams at night.

And on the flip side, left handed people are more prone to insomnia.

So if you have difficulty sleeping and are left handed, then that could be a reason why.

It definitely does.

You know, handedness is a window into how the brain organizes itself before we even take our first breath.

It's a mix of genetics, environment, and these little dashes of randomness.

Yeah, so many things.

And that's just one way to sum up 50 years of neuroscience, I guess.

It is interesting to observe the high rates of lefties in the arts, though.

You know, Oprah, Lady Gaga.
