Here in the USA, we worry about boomers placing massive demands on Social Security and Medicare. Ten thousand Boomers per day will retire, for the next 19 years. Starting NOW!!
That is 3.6 million retirees per year, times 19. Those soldiers were very happy to come home in the 1950s.
However, many of them are obese. Obesity may do here what smoking will do in China; thin out the retirees.
