yup
when you study chinese medicine you differentiate many things by the precise appearance and consistency of fecal matter and you end up discussing these things over lunch at cafes, and soon enough, people are giving you looks from neighbouring tables and look around for tables further away from you . . .
but then, if those folks had stuck around any longer, they could have found out other interesting tidbits, such as, when reviving a drowning victim, you throw them over the back of a water buffalo, spread their legs, and stick a large needle in the perineum (between the anus and the naughty bits)
now doesn't that sound every bit as much fun as mouth-to-mouth?
