Sometimes there are exceptions to the rule.
Many years ago I took my then 85-year-old grandmom to the doctor for an annual checkup. He gave her the traditional lecture about her crap diet: full of saturated fats, caffeine, sugar... And she asked him, "So, I'm 85 and I've outlived every one of my peers. So what you are saying is that if I eat a crap diet I won't live to old age? Well.....?"
Doc: "umm.... er...."
Grandmom, "With respect, young man, I've outlived three of YOU docs despite your fancy diets..."
