alt Hacker News>By contrast, intrinsic mortality stems from processes originating within the body, including genetic mutations, age-related diseases, and the decline of physiological function with age
So we put genetic diseases in the bucket of intrinsic mortality and then found that intrinsic mortality has a heritable component?
Yeah this paper came across to me basically as "if you ignore environmental causes of death, the heritability of death goes up"... which seems kind of circular.
