Is increased life expectancy good or bad?

Generally, increased life expectancy has increased the risk of disease, disability, dementia and advanced ageing prior to death 3, 4. Public and private investment in medical research is primarily focused on reducing death rates, rather than reducing ageing and age-related disease (Table​ 1).
