Coronavirus is an epidemic that hit us at the beginning of the year. But at first, the coronavirus was not perceived as a threat to the entire world on planet Earth. But as soon as humanity realized that coronavirus was serious, social networks were quickly filled with photographs of naked girls. Both completely unknown and world stars. Some of them are wearing medical masks, some are wearing exclusive haute couture masks, some are with open faces. But, the main thing is that the body is naked and all the charms are exposed to the public. Those who do not know history well begin to think that real “stars” and those who for some reason consider themselves such are simply trying to somehow promote themselves during the period of inactivity during quarantine. However, those with a good memory, who can compare, probably noticed that such female behavior is standard for any catastrophic events in history. Women sought to publicly undress in times of crisis long before the advent of photos and videos, before the publication of newspapers, and even more so - before the era of the Internet and Instagram. So, this definitely has nothing to do with PR. Any war, any revolution, any famine, any epidemic - and it’s on you: socialites and not-so-society lionesses have a hard time restraining their acute desire to undress somewhere in a hot place, on the street or just by the window, to show off their body as profitably as possible. “A feast during the plague” performed by women is often stereotypical: wear beautiful underwear, suck in your stomach, stick out your chest and try to appear to as many people as possible. Of course - first of all, for men. Why do they do this? The answer lies in those aspects of psychology that we inherited from our ancestors - primates, apes. Observations by zoologists show: when, during a period of drought, groups of chimpanzees begin to experience a lack of food, they increase their mobility, begin to move, and leave their usual habitats. Because of this, random encounters between different groups of monkeys occur. Of course, this is accompanied by outbreaks of mutual aggression between males, in any case, emotional tension increases and goes off scale. Sometimes it even results in outright fights between groups. At this point in time, the females also change their behavior: they begin to attract the attention of males in every possible way, both their own and strangers passing by. They turn their backs to them, arch their back invitingly, etc. Experts call this behavior of females demonstration behavior. It is believed that in a moment of danger, when there is a lack of resources, competition logically increases between females, who must prove to all surrounding males that it makes sense to save and feed a particular female (and her cubs)¸ and not others. Females from different groups strive not only to prevent the loss of their “target audience of males,” but also to expand it at the expense of other males: suddenly they turn out to be more profitable and successful than the existing ones. Since the females themselves do not fight among themselves, a “beauty contest” is launched, a remote information duel, where the winner has the highest chance of protection from males, increasing her social rank, food and procreation. Most likely, it is this ancient a behavioral complex that comes into play during a crisis forces the most active women to engage in erotic and demonstrative battles and competitions with each other in order to collect the maximum number of likes and comments. This is their “survival” strategy, the strategy of motivating the most successful males for “sponsorship”, the strategy of sending a signal to the outside world: “Look at me! I’m still so young and pretty! It definitely makes sense to save me first! Don’t forget about me, I’ll still be useful to you!!!”This version of the explanation makes it clear why crises in society automatically increase sexual activity, including demonstrative activity in women - this, at the same time, increases their chances of personal salvation, plus.
