thanks everyone for your responses. My health is good but I am feeling more and more stressed at work so I am thinking of cutting back and working part time so that was the reason for the question.
I have a host of medical problems that are genetic and serious. No male in my family has lived past the age of 71. I will be 71 next birthday. If I remember correctly, I break even at about 82. Therefore, I started taking SS at 62 even though I did not need the money. Wife started collecting at 67. Rather take before 70 to fill financial gap before taking mandatory minimum distribution from IRA.
