FuturePundit on the education-longevity correlation, which he presents as more of an intelligence-longevity correlation: "My guess is that as the amount of useful knowledge available to influence longevity has increased (e.g. results from dietary and lifestyle research and new types of treatments that require patients to do much self-administration of drugs and therapies) the advantage of being smart has been amplified. If you get sick and you are smart you have more clinical trials to investigate, diets to try, and treatments to follow carefully. You are better able to understand why a treatment should benefit you and therefore more motivated to stick with it. Rather than follow the advice of one doctor you can seek out multiple experts, ask tough questions, and compare notes with other smart people chasing better treatments. You are better able to see through self-serving advice of specialists who are trying to boost their income. You are more likely to recognize serious side effects of treatments and challenge the wisdom of continued use of a treatment."
