摘要: Aging is the accumulation of changes that increase risk death. can be attributed to development, genetic defects, environment, disease, and an inborn process: aging process. The latter major factor for disease death after age 28 in developed countries. In these countries, average life expectancies at birth (ALE-B) now range from 76 79 years, 6-9 years less than limit approximately 85 imposed by aging. may caused free radical reactions. extensive studies based on this possibility hold promise ALE-B extended >85 maximum span increased.
