Fantastic Voyage: Live Long Enough to Live Forever is a book authored by Ray Kurzweil and Terry Grossman published in 2004. The basic premise of the book is that if middle aged people can live long enough, until approximately 120 years, they will be able to live forever—as humanity overcomes all diseases and old age itself. This might also be considered a break-even scenario where developments made during a year increase life expectancy by more than one year. Biogerontologist Aubrey de Grey called this the "Longevity escape velocity" in a 2005 TED talk.
