Health, as reflected in life expectancy, has increased dramatically globally and especially from 1890 to 1950. For example, the life expectance at birth in the United States in 1890 was 42.5 years. By 1950, it had increased 25.5 years to 68 years. Life expectancy increased 21.5 years in the Scandinavian countries, 21 years in the United Kingdom, and 20.5 years in France. The gain was only 15 years in Japan because it was a poorer country at that time.
