The aging process is thought to be initiated at the cellular level. Among the changes that can occur after a certain number of cell divisions is the loss of a cell's ability to respond to growth factors and other signals. Much research into aging is aimed at understanding such losses, with the ultimate goal of extending the human life span. Not everyone, however, agrees that this is a desirable goal. If life expectancy were greatly increased, what might be the social and ecological consequences?

Body defense malfunctions trigger the body to attack healthy cells resulting in inflammation and cell damage. Cell telomeres shorten and cells are limited in the number of times they can successfully divide. Testosterone levels in males and estrogen levels in females drop. Copy errors during the cell cycle lead to protein dysfunction and cell death. Programmed cell death. Autoimmune malfunctions. Immune system inefficiency. Hormonal changes. Genetic mutations.
