Health and longevity are intimately related to position in the social hierarchy. The lower the status, the higher risk of illness and death, and consequently the shorter the life expectancy. In his book of the same name, Michael Marmot calls this social gradient in health the “Status Syndrome”. So what exactly is the cause of this gradient?
