Don’t be. According to statistics, you’re much more likely to find a weak spot in the second floor, fall through the floor and the ceiling below it, land facefirst in the toilet, get your head wedged in and drown. You’re more likely to stand on a land mine and be flung 1200 feet up in the air, utterly unharmed, until being sucked into the jet engine of a 747 on approach. You’re much more likely to be standing next to a mountain in colorado, and be smothered by an avalanche of breasteses. You’re equally likely to be involuntarily anally probed in your kitchen by aliens. No, not them ones from outer space, them ones from south of the border.

Don’t sweat it, really. Even if you get it, unless you’re old or have a bad immune system, you’re just going to feel like crap for a while.
