Morgan Housel at The Motley Fool lists the 50 reasons we’re living through the greatest period in world history (free registration may be required), and here are the first three (for the rest see here):
1. U.S. life expectancy at birth was 39 years in 1800, 49 years in 1900, 68 years in 1950, and 79 years today. The average newborn today can expect to live an entire generation longer than his great-grandparents could.
2. In 1949, Popular Mechanics magazine made the bold prediction that someday a computer could weigh less than 1 ton. I wrote this sentence on an iPad that weighs 0.73 pounds.
3. The average American now retires at age 62. One hundred years ago, the average American died at age 51. Enjoy your golden years — your ancestors didn’t get any of them.
