got my yearly health check this friday (健康診断 けんこうしんだん)
I need to remember to do my poo samples for the poo test they'll do (検便検査 けんべんけんさ)
便 べん means poo/feces/stool
検査 けんさ test
検 けん by itself means test, so you could read 検便検査 as poo test test if you were being pedantic
for the linux nerds out there 大便 だいべん (daiben, also meaning feces) is close in pronunciation to a certain large distribution that I've heard it's the unofficial name in some quarters
