I am a widow and will be 65 on 12/31/2018. Your maximize benefits program determines that I can claim benefits on my record at 65, still work and then claim survivors benefit at age 66. Survivor benefit will be higher than my own record if I were to work until 70. I understand the survivor benefit does not increase after age 66. If SSA thinks differently, how do I convince them of the strategy that your program has determined?
