De Grey, Aubrey
\di\ \greɪ\, \ˈɔbri\
Aubrey de Grey is an English author and biomedical gerontologist. He is famous for his view that medical technology may enable human beings alive today to avoid death from age-related causes.
He claimed in 2008 that the first human to live to a thousand was probably already alive, and might even already be in their 50s.
