WHAT CAUSES AGING

The rate and progressions of the aging process can vary greatly from person to person, but generally over time every major organ of the body is affected. Aging today is viewed as many processes, and variables that determine lifespan and health. Scientists have proposed many therapies to explain the diversity of the aging process, some of which are:

• Programmed Longevity - aging is the result of switching on and off of certain genes

• Endocrine - biological clocks act through hormones to control the pace of aging

• Immunological - decline in immune system functions leads to infectious disease and thus aging and death

• Wear and Tear - cells and tissues have vital parts that wear out

• Free Radicals - accumulated damage caused by oxygen radicals causing cells, and eventually organs, to stop functioning
