TL;DR: Three biodemographic insights--concerning the correlation of death rates across age, individual differences in survival chances, and induced alterations in age patterns of fertility and mortality--offer clues and suggest research on the failure of complicated systems, on new demographic equations for evolutionary theory, and on fertility-longevity interactions.

TL;DR: Because patterns at the individual level may be simpler than composite population patterns, both theoretical and empirical research may be unnecessarily complicated by failure to recognize the effects of heterogeneity.

TL;DR: It is indicated that aging processes can be quantified in people still young enough for prevention of age-related disease, opening a new door for antiaging therapies.

TL;DR: The heritability of death from coronary heart disease: a 36‐year follow-up of 20 966 Swedish twins shows clear relationships with age, gender, and smoking status.

TL;DR: To compare how well frailty measures based on a phenotypic frailty approach proposed in the Cardiovascular Health Study and a cumulative deficits approach predict mortality are compared.
