Silly question, but how many times have you thrown up in your life? A dozen? Perhaps a couple dozen because you were always sick as a child?
This question dawned on me while a housemate was taking care of her sick boyfriend. He was throwing up and she sought my advice on what to do, because apparently she'd only been that sick once or twice in her life. I was dumb struck at her ignorance, until later it dawned on me that perhaps it was the other way around. As odd as it sounds, I’ve come to see myself as an outlier and perhaps even an expert at vomiting.
While the average person throws up less than once per year, I’ve managed close to ten times that. Thanks to my food allergy, I've thrown up on over a hundred separate occasions and probably closer to twice that. And without getting too scientific about this, I'd venture a guess that this puts me at least a couple standard deviations out from the norm.
