Life expectancy indicates the average length of life. It does not indicate how long a specific individual will live. An individual's life expectancy can be affected by events such as accidents, epidemics, and wars, as well as experiences during their life (eg smoking, diet, environment). Life expectancy will also vary by ethnicity and socioeconomic position.
