Today in human geo class we took notes on a video explaining 200 years worth of global health in 200 countries in four minutes. Hans Rosling teaches global health. The life expectancy is on the x axis on a chart. The ages usually range between 25- 75 years. The y axis is the income per person ad ranges from $400-$40,000. In 1810 every country's life expectancy was below 40 except for the UK and the Netherlands, which were the richest countries at the time. The industrial revolution is causing the industrializing nations are increasing their life expectancy, and African and Asian colonies life expectancy did not increase because their nation did not take part in industrializing. World War I, World War II, and the Spanish influenza drastically decreased the life expectancy. 1948- end of war and countries are extremely spread out on the chart; they continue to increase their life expectancy. 1990's- Asian countries rapidly increased and in the present there are hardly any countries below 50 years for life expectancy.
