Here's another implication of longevity. People often plan to leave money to their children upon their death. Their children may well be retired by the time they inherit. Parents may want to consider more giving during their lifetime, at a time when their children may be more in need of the money and the parents can enjoy watching the benefits of their gifts. It also gives you a chance to see how well they financially handle your gifts.
Employment is another changing aspect of retirement.
Retirement in the future may no longer be a matter of quitting work cold turkey at a particular age. Retirees may want to start their retirement years by cutting back gradually on work. For some, this will be a financial necessity. But for others it may be an emotional and intellectual necessity. They find work an enjoyable, creative, life-affirming endeavor.
