«We expected some differences, but I was impressed by the magnitude we observed — a 13 percent increase
in median life span for the mice on a high - fat versus high - carb diet.
Also, my understanding is that a 25 % increase
in median life span would bring us up to 100, which would mean a reduction of mortality at very old ages too.
Barbara: a 25 % increase
in median life span would not likely bring us up to 100: our current population median lifespan is already artificially lengthened by medicine, from vaccines (which also impact late - life mortality by reducing lifelong inflammatory burden) to more obviously late - life medical interventions.
