If we had no advanced medical care we might live to an average of 78 years instead of 78.1.
I estimate 45% social factors (money, education, work and geography), 40% neighborhood shaped choices (exercise, diet and smoking), 12% ‘fixed’ biology (gender and genetics), and no more than 3% healthcare determine average health in rich countries. Society, not biology, underlies 85% of human health.
Healthcare may make a 2 month difference, while social factors make 5 year differences in lifespan.
Almost all other industrialized nations and some poor ones now outlive us.
