Life Expectancy Science
- Life tables — Actuarial tools that estimate probability of death at each age for a population.
- Global trends — World average life expectancy rose from about 30 years in 1900 to over 70 today.
- Determinants — Sanitation, vaccination, nutrition, and income are major drivers of lifespan gains.
Philosophical Traditions
- Memento mori — Stoic and later Christian practice of reflecting on death to clarify how to live.
- Epicureanism — Held that death is 'nothing to us' since we do not experience it once it occurs.
- Existentialism — Thinkers like Heidegger framed authentic living as confronting one's finitude.
