Approximately 35% of the factors that influence life expectancy are inherited. Accelerated aging is therefore usually associated with genetic abnormalities. None of the accelerated aging syndromes, however, leads to a uniform, systematic “speeding up” of the aging process. A number of genetic disorders can lead to premature or accelerated aging (also referred to as progerias), including Down syndrome, Hutchinson– Gilford syndrome, and Werner’s syndrome. (more…)

We do not realize the mechanisms of biological aging or the reasons for aging are the limits of the estimated averages life expectancy of people are very empirical. The forces of natural selection with age, as in natural populations, few people survive beyond the age of reproduction. In recognition of these ideas, some would suggest an antagonistic pleiotropy hypothesis that the genes of a disadvantage in a population is not necessary to the reproductive phase, after which take place occur at the population can get. The environment is hostile, and individuals compete for resources. (more…)

Specific contents of education reflect general cultural values and preferences of social environments and milieus, social change, and societal progress. (more…)
