Here only it is quite "aggressive". Here we are about ecology, sociology, stress, tempo, rhythm of life. And of course, that public opinion about human longevity, as described above.

Thanks to advances in science, medicine, and managed to cope with the various epidemics (plague, cholera), the system of vaccination, antibiotics – maintained and allowed to grow for many generations of people. All this led to the fact that people began to live longer than in the past, but in the end, a new problem – the rapid aging of the species population.
