Maybe don’t read this if you are eating something:
The human body has some interesting features. But it is our reactions to parts that leak fluids that create some curious social and cultural rules based on the level of perceived appropriateness and acceptability of expulsion. We’re funny about tears and sweat, both completely natural and harmless. There are other bits with some peculiar contradictions and I think it has something to do with the velocity of the fluids leaving the body. Things that drip or ooze take on a passive act but if it shoots out it is active and purposeful. For example a runny nose is a slow drip and generally frowned upon, but a vigorous nasal clear on a football pitch or bike is completely fine. Saliva is a bit the same, a slow drool is not so cool but spitting can be an art form. Some leaks depend a bit on specific plumbing of a particular set of organs. The menstrual cycle for one gives those with that set of plumbing a complicated set of leaks. Bleeding monthly is quite frankly a very poor design. Bladder leakage definitely not as acceptable as a long strong stream and obligatory ‘ahhhhhhh’ if busting. But I am sure I am missing some other form of leak or complementary explosion….ohhh…this is so hard…it’ll come to me.
