Life Extension means increment in average or maximum lifespan, mostly in human beings, by slowing reversing or down the process of aging. Average lifespan is firmed by age related afflictions like cardiovascular disease or cancer and susceptibility to accidents. Conservatory of average lifespan may be achieved by exercise, good diet and avoidance of hazards like excessive eating of sugar and its containing foods and smoking. Maximum lifespan is firmed by the aging rate for a type inherent in its genes and most likely by certain atmospheric factors. At present, only the widely recognized way of expanding highest lifespan is calorie restriction.

Researchers of this field are known as Biogerontologists. The researchers search for understanding the nature of aging and they expand treatments to repeal aging processes or to at least decrease it, in order to improve the health and keep the youthful vigor at each stage of life. The people who take benefit of life extension findings and search for applying them on themselves are known as Longevists or life extensionists. The primary strategy of life extension is to apply anti aging methods for living long to benefit from a whole cure. It gives very rapid benefits to the user.

Many life extensionists and believe that coming breakthroughs in hankie rejuvenation with organs replacement, stem cells and molecular repair will get rid of all aging and disease and also allow you for total rejuvenation for getting a youthful condition. Whether these breakthroughs may occur within the coming some decades is almost impossible to predict. Many biomedical gerontologists and life extensionists place to be chronically preserved on legal death so that they may await the time when future medicine may get rid of disease rejuvenate them till a youthful condition and repair the damage caused by cryonics process.

Life extension History: - Aging Association of America was founded in 1970, under the momentum of Denham Herman inventor of the free redica theory of aging. Denham wanted an institute of Biogerontologists that was dedicated to research and to sharing of information among scientists who are interested in expending human lifespan.

Scientific controversy regarding Life Extension: - Although Bernard stroller and Alex comfort have been retrospectively said as anti aging gerontologists. Dr. Denham Harman also spent many years in experimenting on Life Extension with antioxidant, and he was able to set up only that antioxidants can expand mean lifespan; he was incapable to demonstrate an effect over maximum lifespan. Non antioxidant nutrients like selenium, zinc and chromium are more effective and they have comprehensive maximum lifespan.
