If 50 is the new 30, then 85 could be the new 65. According to a new survey, Americans aged 85 and older are still working, more than in any other time in history. The survey found that more than 255,000 Americans in that demographic are still slaving away. As people live longer and retirement savings dwindle, these oldsters are finding work in jobs less physically demanding, like sales and management. If 65 is the new 45, then I won’t be retiring for another 31 years.
