Life is dangerous: You could slip in the shower, get hit by a bus, mauled by a bear or drown in breasts (it happens, look it up). It always pays to be safe, and a life lived cautiously is a life lived long. For those of us who walk the cautious road and avoid the three lethal B's--buses, bears and breasts--wherever possible, life should be more or less safe. Right?
Not in the slightest. See, it turns out just waking up in the morning can be as dangerous as any drunken all-night lion-punching marathon, and you can just as easily kill yourself sneezing as you could playing Gun Hockey (and at least Gun Hockey's fun... well, up until Shotgun Overtime, anyway).
What, did you think that was a throwaway example? No, sneezing will jack your shit up. Though it's one of those annoying biological functions that serves a deceptively useful purpose (it's your body's way of getting dirty snot out of it) and often provides a convenient excuse for spitting in your enemies' faces, it's still basically a time-bomb planted inside your nose.
A sneeze can rupture your ear drums, break your spine or straight up murder you. It's like Mortal Kombat inside your face. People have slipped discs in their backs, broken ribs and triggered heart attacks from a simple sneeze. And keep in mind, we're not talking about fragile people who were also at the end of a long battle with a terminal disease. These were just normal people, going about their normal lives, until they got a whiff of pepper and woke up six hours later in a dumpster laying atop their shattered limbs.
