'''Aubrey de Grey''' is a transhumanist and [[cryonics|cryonicist]] who posits that the first person to live to 1,000 is likely already alive and that someone born around the year 2000 has anywhere from a 50 to 80 percent of living much longer than the current lifespan, depending on how much funding [http://sens.org/ SENS] and related life extension programs receive soon.<ref>Caspar Llewellyn Smith (31 July 2010).

Aubrey de Grey famously predicts that humanity will reach longevity escape velocity around 2035, he also proposed a theory for the ways to cure aging, called strategies for engineered negligible senescence, maintaining that all causes of aging can be cured with proper strategies that are within the reach of current technological progress; however, many mainstream scientists believe that his strategies for engineered negligible senescence is a [[fringe#Scientific fringe|fringe theory]];<ref>{{Cite journal | first1=H. |last1=Warner | first2=J. |last2=Anderson | first3=S. |last3=Austad | first4=E. |last4=Bergamini | first5=D. |last5=Bredesen | first6=R. |last6=Butler | first7=B.

==Longevity escape velocity==
Aubrey de Grey predicts that the humanity will reach longevity escape velocity (LEV) around 2035, that is, the situation in which the remaining life expectancy of humanity always increases more than one year in each year. His prediction of the timing of LEV has been rather constant over years. In short, longevity escape velocity is a form of biological immortality attained by constant engineering on the human body.

However, in reality, the increment of life expectancy is slowing down, and it is unlikely that the percentage of people living to 100 years old will ever exceed 15% for females and 5% for males without any means to slow aging<ref>{{cite journal |author1=S.

==Criticisms==
{{main|Transhumanism#Radical life extension}}
[[PZ Myers]] believes immortality is impossible because the [[second law of thermodynamics]] leads to inevitable decay in any living system.<ref>[http://freethoughtblogs.com/pharyngula/2013/07/22/a-short-argument-against-immortality/ A short argument against immortality]</ref>

=== Allegations of sexual harassment ===
In 2021, de Grey was placed on administrative leave by SENS Research Foundation over sexual harassment allegations.<ref>The Times: [https://www.thetimes.co.uk/article/anti-ageing-guru-aubrey-de-grey-accused-of-harassment-xm0l8gnvp Anti-ageing guru Aubrey de Grey accused of harassment], 12 August 2021</ref> Shortly after, he was removed from his position as he seemed to interfere with the sexual harassment investigation.<ref>STAT: [https://www.statnews.com/2021/08/22/sens-research-foundation-removes-aubrey-de-grey/ SENS Research Foundation removes Aubrey de Grey over concerns he was interfering in sexual harassment investigation], 22 August 2021</ref>
