This chapter describes some of the science behind the strategies for engineered negligible senescence (SENS). It argues that Aubrey de Grey has presented substantial arguments about how we might put an end to aging to be taken seriously. The reach of SENS clearly exceeds the grasp of early twenty-first century medical science, and belongs in the same category as putting human colonies on Mars and cloning woolly mammoths. Kurzweil has presented the idea of life extension before with his theory of a machine-mind that will colonize the universe as the final consequence of the law of accelerating returns. For him, however, extending biological existence seems merely a delaying tactic, the purpose of which is to keep us around until the advent of machines that will become more secure vehicles of our identities.

Keywords:   engineered negligible senescence, SENS, Aubrey de Grey, aging, medical science, Kurzweil, life extension, machine-mind, accelerating returns, machines
