xxx: long ago in some medical collection read an article, there the author compared the statistics of prostate diseases in Russia and the Arab Emirates. And I concluded that in the Arab Emirates, men are less likely to be excited in the empty, because they do not see the naked female bodies, and therefore are less exposed to stagnant phenomena.
The author did not compare the climate.
--------
Continuing the trend, we conclude: men from the tribes of Pigmeans, Masaians and other nationalities, in which everyone walks naked, die naked from prostatitis (well, unless the lion has not hit before) )))
