It is estimated by the estimation people--no one actually knows who they are, but they help shape our culture in lotsa ways--that the average person swallows 6 spiders in his/her lifetime. If yer above average it may mean ya swallow ten or eleven, and if yer below average ya may swallow one or two. Superiorly above average people eat them by the dozens, but because they really screw up the stats, the folks who estimate jus' don't include them. Strange, huh?
