The newest iteration of the Global Burden of Disease study, which tracks the prevalence of deaths and diseases worldwide, contains some good news: On average people are living about a decade longer than they were in 1980. But there’s a catch: Health hasn’t improved as fast as life expectancy overall, which means that for many, those long, final years are spent hobbled by illness and disability.
