I think the point is that any dietary or lifestyle recommendations to achieve a long life need to be reassessed. Do recommendations to reduce intake or intermittent fasting rely on unverified population ages?

What do people like Queen Elizabeth, Warren Buffett, Rupert Murdoch do to remain healthy and still working at their age?
