From the evolution standpoint, modern humans have entered a stage of increased advanced aging as the proportion of people in older age groups continues to grow. The limit of human life expectancy is now being recorded at 110-120 years with a maximum reliable life expectancy going as high as 122 years. However, the main task of modern science is not to increase the human life span alone, but to increase the average human work/productivity period. Therefore, scientists are researching medications and other methods to increase human work productivity. The increase in vitality resource and increased working life span will enable an increase in the working age population, which is extremely important in terms of socio-economic problems. The current techniques that enhance quality of life, reliable and scientifically valid as they are, include the following: caloric restriction, use of antioxidants and vitamins, telomerase activators and other ones too numerous to mention.
