I retired from Nursing at 76. Nursing is more physical than you might think, but it certainly does not compare to the physical demands of many other occupations. Admittedly, I stopped working 48 hrs. per week in my 60s, but my debts said I needed to continue part-time. The idea that "one retirement age fits all" is seriously flawed. Some folks can and want to continue beyond 65, whereas others are clearly worn-out and should be able to stop and enjoy what years they have left.
