Sure, head down to your local Social Security office when you reach age 62...get ready-some very long lines!

If you decide to delay benefits until age 70 you'll get a 76% increase, yeah a huge boost.  And, for those whose full retirement age is 66, collecting Social Security benefits at the earliest age, 62, results in a 25% reduction in benefits.  Those who wait until the lastest age, 70,receive an extra 32% in delyed retirement credits.
