attached article produced by people who make their careers out of such studies...but I'm not sure you're smart enough to even grasp the reality.

btw, take a look at Dr. Fauci's recent 4 hr Congressional Hearing...he took on Congressmen/women half his age (he's 83) and not one of them landed a 'punch' on him. Do you really think YOU could match his "Fund of Knowledge" for Infectious Diseases, Virology, Microbiology, Epidemiology, Government Requirements, International organizations and their scientists, etc., etc... Very few people are as mentally capable...at any age..as he is right now.

Not all 77-80 yr olds are created equal...witness Donald J. Trump and his bizarre word salads on the campaign trail.
