Turns out it can't. I know, I was a little bummed too.
So then I googled, "Can sneezing kill you?" because, let's face it, we're kind of fragile things, we humans.
Alas, sneezing rarely leads to death (although if you're sick and you sneeze on a really old person, there's a chance).
But don't be disheartened. Sneezing can jack you up in lots of other wonderful ways. Scientists estimate the speed of a sneeze (band name alert) at 650 mph. Not surprisingly, it's kind of stupid to try and hold this sort of force back. You can bust an eardrum, tear blood vessels, damage your sinuses, or even cause a brain hemorrhage. (Never realized stifling a sneeze and watching Joy Behar had so much in common.)
And even if you don't hold them back, sneezes can be strong enough to cause a whiplash effect, leading to pulled muscles, bitten tongues, and even broken teeth.
In short, sneezes are bad ass.
And occasionally, so is research.
Here's a video of a baby panda sneezing and scaring all hell out of its mother:
And in a "you-can't-make-this-sort-of-thing-up" blessing, here's a news article about a girl who can't stop sneezing, a condition called Paediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcus, AKA...yep...PANDAS.
