I won’t enter the longer life span as rebuttal, as you asked, but I will note that it is (unfortunately for them) african-american and hispanic-american folks who drag our life expectancy stats even further down. If you did the life expectancy of just white people, it would be much higher, so I read.
So that makes me think that at least whites as a group in this country are living healthier than blacks/hispanics.
We all have access to the same medical care and pharmaceuticals.
As you might guess from my responses, I have a bias toward certain industries that, I feel. don't always have the health/well-being of the consumer as the first consideration.
