Aubrey De Grey does not see the aging process as inevitable. His controversial research focuses on ways to rejuvenate the body’s tissues and provide people with an indefinite lifespan.

His goal is to identify all of the components that cause human tissue to age or, as de Grey puts it, to develop "Strategies for Engineered Negligible Senescence" (SENS). To date, he has identified seven types of molecular and cellular damage caused by essential metabolic processes. 

In July 2005, the MIT Technology Review challenged scientists to disprove de Grey's claims, offering a $20,000 prize (half the prize money was put up by de Grey's Methuselah Foundation) to any molecular biologist who could demonstrate that "SENS is so wrong that it is unworthy of learned debate." The challenge remains open.
