Sure, I understand what you are saying. Those are actually significant findings, though. Keep in mind how good we are at keeping people with progressed heart disease alive. The relatively few years' reduction in lifespan masks, in my cases, early onset of heart disease and years of expensive emergency response, frequent hospitalization, transplants, reduced quality of life, and so on. Better is to look at large meta studies about bmi, smoking, diet, and physical activity as they affect rates of disease as well as mortality. I quickly searched and found many results.

Respectfully, I haven't said anything about living until a very old age. I am only talking about a few diseases and I understand there are a lot of ways to die. I have also said the morality of not trying to extend lifespan is subjective.
