Lifetime totals depend on assumptions

These large figures are not universal biological averages: life expectancy depends on year and country, word counts depend on who was measured and how, and sexual frequency varies widely by person and age. For example, the UN estimated global life expectancy at birth at 73.3 years in 2024; this is not a prediction for every individual. Exact lifetime totals for words spoken or sexual encounters cannot be presented as fixed facts about an “average person.” The illustration is AI-generated.
