How long a retirement should you plan for?

Here in Connecticut, in East Hartford, lived the world's oldest person, Emma Tillman. Alas, she only held the crown for four days.

If Ms. Tillman began receiving Social Security benefits at age 65, that would have been during the Eisenhower administration. Fifty years sure is a long time to be retired. Few, if any, have the financial resources to live without working for so long a time.
