Country-specific standards, units, or regulations:

Male: 75.7 years (2023). Female: 80.9 years. Varies by state (Hawaii 81.3; Mississippi 71.5). Mortality increased post-COVID. Socioeconomic gap widens.

Male: 79.5 years. Female: 83.1 years. Regional variation (London higher, North lower). Inequality in life expectancy widening (2010–2020 stalled, post-COVID recovery slow).

Factor	Years gained/lost
Smoking	-10 years
Obese (BMI≥30)	-2 to -4 years
Regular exercise (≥150 min/wk)	+3 to 5 years
Mediterranean diet	+2 to 3 years
Strong social connections	+3 years

Can I predict my life expectancy?

Approximately. Health factors (BMI, blood pressure, cholesterol, smoking, exercise) predict better than averages. Genetics matters but ~25%; environment/behavior 75%. Online calculators available.

Should I plan finances assuming longer life?

Plan conservatively: assume 90+ if you want certainty. If average 80, plan 85–90 to have buffer. Longevity risk = money running out. Annuities/pensions provide longevity insurance.

How does health affect life expectancy?

Huge. Smokers lose ~10 years. Obesity ~5–10 years. Sedentary ~5 years. Chronic disease (diabetes, heart disease) 5–15 years. Conversely, exercise, normal weight, no smoking = 80s–90s realistic.
