Education can increase life expectancy by several years according to research on aging and longevity in Denmark. People with higher levels of education had longer life expectancies. The reasons for this are unclear. Social hierarchy, health literacy, lifestyle and behaviors are all possible explanations of the education and life expectancy link.

Mental health can be a great anti-aging technique. Seniors who had a strong, positive sense of meaning in their lives had less age-related disability than those without this mental health factor.
