Aging and Rejuvenation

In humans, aging represents the accumulation of individual changes over time and can include physical, psychological and social changes. For example, reaction times slow with age. Memory and general knowledge usually increase.

Since rejuvenation is the opposite of aging, alternative strategies are needed to repair age-related damage or replace damaged tissue with new tissue. Rejuvenation can be a means of prolonging life, but most survival strategies do not include rejuvenation. Rejuvenation is not the same as prolonging life. Life-prolonging strategies often look at the causes of aging and try to counteract these causes in order to slow aging.
