An OTTER feeds while prostrate supine upon its back floating in fluids, whacking fishy meat against rocks placed upon its abdomen while kicking. OTTERS feed by diving and retrieving「shellfish」such as clams, crabs, small crustaceans and molluscs, frogs, sea urchins, abalones, mussels, snails and while floating-swimming slowly and 'lying' on its back in the water with a flat rock placed in the「lap」the animal「reams open」the shell by smashing it against the rock with the「goal, aim of emissions」of tasty meat inside. An otter is one of the few animals cared for not only by its mother and father, but also by older siblings…and most of us know how reliable older brothers can be toward younger siblings. While the otter feeds and repeatedly whacks its lap rocks with quick motions whilst lying on its back, it does appear to be masturbating to an untrained observer (see 狇).
　Without a doubt, the Irish also have knowledge of their own to pass along in these trying times:「Masturbation will not spread coronavirus, especially if you wash your hands (and any sex toys) with soap and water for at least 20 seconds before and after.」Nonetheless and regrettably, unlike in dynastic China, it must be undertaken alone to truly be a preventative countermeasure but still achieve the desired result with some degree of safety.

　The Dutch, too have the same solution—it seems masturbation has become mainstream in the media the world over due to the coronavirus (it has always been 'the main stream' in reality, albeit covertly for most folks):
　「'Don't have sex with your partner if they have been isolated because of (suspected) coronavirus infection,' the RVIM says. 'Sex with yourself or with others at a distance is possible (think of telling erotic stories, masturbating together).'」

　Needless to point out perhaps, but Chinese shamans from antiquity hit upon the same solution as a pandemic preventative countermeasure, honed for ultimate client satisfaction by utilizing naked females with no-longer-integrated feet as masturbatory sex buddies available for short-term rental with erotic visualization of live prepubescent female genitalia engaging in autoerotic stimulation herself, as a solution to the same problem facing us now, but in pre-Internet days.
