Hayflick suggested that the aging process was by a biological clock, which includes all living cells, controlled. The study found that in 1961 human fibroblast cells (lung, skin, muscles, heart) have a limited lifespan. Nutrition appears to affect the rate of cell division are: cell consists of 50 departments in a supercharged year, while the cells fed up to three times longer than normal cells to divide. (more…)

Aging in human is a combination of two ageing processes: development or maturation, and senescence aging or decline. Development or maturation is the positive aspect of aging; humans typically acquire greater wisdom, experience, and expertise in specific fields as they grow older. Senescence aging, on the other hand, (more…)

Although we have not identified the genes controlling human life span, there is a genetic element called a telomere that clearly regulates the replicative life span of human cells in culture. A telomere is a simple DNA sequence that is repeated many times, located at the tips of each chromosome. Telomeres are not genes, but they are needed for the proper duplication of the chromosomes in dividing cells. (more…)
