This life extension talk has all the hallmarks of a grift or confidence trick.

Cons succeed for inducing judgment errors—chiefly, errors arising from imperfect information and cognitive biases. In popular culture and among professional con men, the human vulnerabilities that cons exploit are depicted as 'dishonesty', 'greed', and 'gullibility' of the marks. Dishonesty, often represented by the expression 'you can't cheat an honest man', refers to the willingness of marks to participate in unlawful acts, such as rigged gambling and embezzlement. Greed, the desire to 'get something for nothing', is a shorthand expression of marks' beliefs that too-good-to-be-true gains are realistic. Gullibility reflects beliefs that marks are 'suckers' and 'fools' for entering into costly voluntary exchanges. Judicial opinions occasionally echo these sentiments.
