Well, according to Suze Orman just about everyone should wait until 70 years of age.  I read the same AARP article as Sean and was a little concerned also by her advice.  Social Security planning is not a one-size fits all solution.  Waiting until 70 may make for a worthwhile mass media sound bite (and, logically, one should wait if they can afford to), but many folks can't or shouldn't wait.  Why shouldn't they wait?  Consider the following:

• Maybe longevity does not run in your family;

• Maybe you have a chronic illness/condition;

• Maybe an individual can't work or can't find work commensurate with their education/experience level;

• Retirees who have too much debt; and/or

• Folks who are willing to accept a lower standard of living so they don't have to go to work anymore.
