It is NOT simply a matter of deciding at what age one will retire and start benefits, especially for someone who is currently married,widowed or divorced. Here is a link to a great tool to explain the options and help decide.
"AARP announced the launch of its Social Security Benefits Calculator, a unique interactive tool designed to help people make the complex but critical decision of what is the best age to claim Social Security benefits to meet their financial goals. The calculator is part of AARP’s new “Ready for Retirement?” effort, a ten-step approach to envisioning and planning for a secure retirement, which includes creating a budget and preparing for the unexpected."
