Exercising sound judgement, behaving like a wise sage engaging in cheerful, risk-free activities mixing exchanges with friends. Perhaps a laugh a minute, eh?
　CHEERS, mate…male masturbation as SAGACIOUS prevention of prostate cancer:「Two relatively large studies of this question, reported in 2003 and 2004, yielded good news for sexually active men: high ejaculation frequency seemed to protect against prostate cancer.」
　「As part of Harvard's Health Professionals Follow-up Study, 29,342 men between the ages of 46 and 81 reported their average number of ejaculations per month in young adulthood (ages 20–29), in mid-life (ages 40–49), and in the most recent year. Ejaculations included sexual intercourse, nocturnal emissions, and masturbation. Study participants also provided comprehensive health and lifestyle data every two years from 1992 to 2000. The scientists found that men who ejaculated 21 or more times a month enjoyed a 33% lower risk of prostate cancer compared with men who reported four to seven ejaculations a month throughout their lifetimes.」
　「An Australian study of 2,338 men came to a similar conclusion. In all, men who averaged 4.6 to seven ejaculations a week were 36% less likely to be diagnosed with prostate cancer before the age of 70 than men who ejaculated less than 2.3 times a week on average. The study found no connection between prostate cancer and the number of sex partners. (An earlier study, however, found that men who had sex with 30 or more women were two to three times more likely to develop prostate cancer than men with only one partner.)」

　It's a mighty poor dog that won't wag its own tail.
　「Evolutionary biologists have traced the origins of masturbation to ancient primates that predate the first humans by tens of millions of years. The findings emerged from what scientists believe is the largest dataset ever compiled on the activity, and confirm that humans arose on a branch of the tree of life replete with self-pleasuring predecessors. 'What we can say is this behaviour was present around 40m (40,000,000) years ago, in the common ancestor of all monkeys and apes,' said Dr Matilda Brindle, the lead researcher on the study at University College London. 'It's not that some species woke up one day and started doing it. This is an ancient, evolved trait.' '…This is such a common behaviour across the animal kingdom, I find it absolutely baffling that nobody has researched it before,' said Brindle. 'For people who think masturbation is wrong, or unnatural in some way, this is perfectly natural behaviour. It's part of our healthy repertoire of sexual behaviours.'」

　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.
