- Sleep duration and mortality · How habitual sleep length, sleep regularity and sleep disorders relate to the risk of death in long-term population studies.
- Naps · A nap is a short sleep taken during the daytime; short naps improve alertness, while regular naps of an hour or more are linked to a higher risk of death.
- Resistance training · Resistance training is exercise in which muscles work against a load, such as weights, elastic bands or body weight, to build strength and muscle.

- Oral health · Oral health is the condition of the teeth and gums; gum disease and tooth loss are linked with heart disease, dementia and earlier death.
