A scientist specialising in anti-ageing research has made the bold claim that he will live to be 150.

Dr Alex Zhavoronkov takes 100 drugs a day and regularly monitors his blood biochemistry and cell counts in pursuit of his goal.

Zhavoronkov is the director of the Biogerontology Research Foundation think-tank and the author of The Ageless Generation: How Advances in Biomedicine Will Transform the Global Economy.

The scientist believes the psychological impact of ageing is the greatest barrier to longevity and he sees challenging our expectations of ageing as a key part of his work.

In an interview with The Telegraph he said: “People form their longevity expectations primarily using their family history and country averages and are not prepared to change their expectations quickly.”

He also makes the point that people reaching record ages now lived through much tougher conditions than exist today.

In January Zhavoronkov made a million dollar bet with fellow longevity expert, Dmitry Kaminskiy, over who could live the longest.

Longevity research, which was once seen as a fringe science, is on course to become a major biotech industry.
