Back in the 1980s, these two writers/researchers/biochemists were major champions of mega-vitamin therapy and other iffy propositions they claimed would radically extend lifespans and general health.
I recall a rerun of “Donahue” in which they hailed the magical properties of their Fountian of Youth cocktails, at which point an audience member bellowed, “If this stuff works so darn well, how come you two look so terrible?”
Yup, proof that they are 71. Life expectancy in the USA is 78.7 years. So, nothing amazing. If I see 101 or something… OK. I had an aunt that had breats cancer that made it to 89. Grandma smoke and is in her 80’s. Soooo… 71 is kinda “what’ev”.
