Health: Along came modern medicine that prolongs human life.
Along also came FLUSH TOILETS, Running CLEAN Water, MORE FOOD and LESS OVERCROWDING.
And this also had a dramatic effect on the reduction of disease and lower mortality for sick people.
In the THIRD WORLD, malnourished children die from Measles. But virtually ZERO children die from
Measles in USA.
So PROSPERITY = better nutrition has a lot to do with people recovering from illness and therefore
people live longer.
