Ending Aging: The Rejuvenation Breakthroughs that Could Reverse Human Aging in Our Lifetime is a 2007 book written by biogerontologist Aubrey de Grey, with his research assistant Michael Rae. Ending Aging describes de Grey's proposal for eliminating aging as a cause of debilitation and death in humans, and restoring the body to an indefinitely youthful state, a project that he calls the "strategies for engineered negligible senescence" ("SENS"). De Grey argues that defeating aging is feasible, possibly within a few decades, and he outlines steps that can be taken to hasten the development of regenerative medicine treatments for each side of aging.
