I've never really completely bought the "low access to healthcare" argument since heart health depends mostly upon good diet and exercise, which are available to many of the undereducated. Yet across the board, those with higher ed live about 9 yrs longer. One theory is that many of higher ed cohort have the genetics for "slow growing" (a kind of built in delayed gratification) and that this group tends to fall into a higher ed category (while the fast growing, wired more to grow faster and survive childhood diseases, don't) The "lower education" cohort probably has a worse diet (an American and Western thing?) as it tends to eat more packaged/processed food...this doesn't help. A doctor's heart disease intervention may be overrated, judging by recent info re: statins and stents? Another article, Mr. De Winter?
