Longer human lives have led to a global burden of late-life disease. However, some older people experience little ill health, a trait that should be extended to the general population. Interventions into lifestyle, including increased exercise and reduction in food intake and obesity, can help to maintain healthspan. Altered gut microbiota, removal of senescent cells, blood factors obtained from young individuals and drugs can all improve late-life health in animals. Application to humans will require better biomarkers of disease risk and responses to interventions, closer alignment of work in animals and humans, and increased use of electronic health records, biobank resources and cohort studies.

Fried, L. P. et al. Frailty in older adults: evidence for a phenotype. J. Gerontol. A 56, M146–M157 (2001). The Fried criteria were among the earliest multi-domain definitions to index frailty, including shrinking (weight loss), muscle weakness (handgrip strength), poor endurance (self-reported exhaustion), slowness (gait speed) and low physical activity (kcal expended per week), estimated in community-dwelling people over 65 years, and this definition of frailty is now widely used in large epidemiological and clinical studies and formed the basis for the development of novel indexes to predict elderly people who have a higher risk of incidences of disease, hospitalization, falls, disability and mortality.
