Researchers of life extension are a subclass of biogerontologists known as "biomedical gerontologists" (Wiki, LE). Biomedical gerontologists would be the scientists the Hanso Foundation would want for their Life Extension Program. Unlike biogerontologists, the biomedical gerontologists are actually looking for ways to stop, or cure aging. Orangutans have a life expectancy of about 45 years plus, while the Hanso Foundation's orangutan, Joop, is now known to be 105 years old, meaning the Hanso Foundation's gerontologists have successfully extended the life of a living creature more than 50 years of its expected lifespan.
Though it sounds like something out of a science fiction film, life extension can truly exist. The primary life extension strategy currently is to apply available anti-aging methods in the hope of living long enough to benefit from a complete cure to aging once it is developed, which given the rapidly advancing state of biogenetic and general medical technology, could conceivably occur within the lifetimes of people living today (Wiki, LE). Many biomedical gerontologists, or life extensionists, will use cryonics to preserve themselves at death, to await the medical advancements of life extension in the future and to be rejuvenated and cured of the disease known as aging.
When talking about life extension, morality and ethics come into play. Is it morally just to go against nature and extend peoples' lives much further than they're intended? Some would say no. "Playing god" is the ultimate immorality. Taking all the power unto yourself and distributing out longer lives... by attempting immortality, you're commiting immorality. There's just no way around it.
For example, what happens when everyone lives and no one dies? Overpopulation. The Earth wouldn't be able to sustain it. With too many people, resources would die out sooner, land would become exceedingly smaller, the Earth just would not be able to take it. You can't have exponential growth without exponential decay. Life extension would throw off the balance of the world, and without balance, without death's complement to life, instead of everyone living longer happier lives, the world would cease prematurely due to the hubris of mankind. And, no one wants that.
