Being woman is already miserable, but a man is not also any less handicapped. Everybody knows a woman lives a life longer than a man. Today scientists advance a very simple reason: the competing for lover makes man debilitated or be canceled.
"Most of countries, women live longer than men, and the difference in sex of longervity is recognized at least the middle of 18 th century", said Daniel Kruger in Michigan University , "that is not recent tendency, but it is rised from in the old days in evolutionary history".
With chimpanzee, the death ratio rockets up with male of 13 ages in which he reproduces and scrambles for position in his society. Males in many species must struggle violently for winning the right to kiss and cuddle females. The gaudy feathers of birds are themselves an example about biological effort aim at objective success in love that they must pay the penalty for it with vital force and life shortened.
In this plot of natural selection, the evolution made take form the properties that help organism keep the best genetic collection, but sometimes harm each individual.
Men nowadays must not wrestle for having beauty however the pressure of success in sex don't change matter any. Only measure is transformed.
Though societies modified profoundly from generation to another but some thing remains the same. Women still bear responsibility for taking care of families and having babies. So like ancient they have to be careful in choice of their life partners. And infer logically results from being popular with females, males must engage in hazardous behaviors similar to numberless in millennium before as well as all other animals.
In the primitive dynasty, with power-cane is a way to occupy candidate. Nowadays, another way as the same value is economic potential to purchase a shiny new SUV. "Men always compete with others for source of force and position in society, because of that criteria men are attached much importance to selection of lovers", said Kruger.
The pressure of competition for lover can be formidable deal with males who are entering period of mature age. And it is similarly, the daring of youth lays the foundation of development of social mankind system. A symbolic example, youth man is always one of the pioneers of each war.
An investigation last year also came to the same of conclusion that is: the adventure, aggressiveness and extreme emotion of the youth usually relate to longevity of men directly.
Among the disadvantageous behaviors include even smoke, bad driving and violence. The realities also prove that the low position in society of men strongly impact on the death rate of men more than of women.
