People born before 1950 who ate 4 eggs a day (fried in butter) plus bacon, and were inhaling smoke, smog and lead (leaded gasoline) every day, and did and ate any number of other “bad for you” things every day, are dying these days in their low to mid 80s. People born later will likely have life expectancies well into their 90s, assuming they don’t live in Chicago or Baltimore. All this diet research is just useless tinkering around the edges but it keeps the grant money flowing.
My grandfather lived to 84 and ate pork fat in everything..............
