this alludes to the full retirement age, that it's the age at which a person may start to receive full or unreduced retirement benefits.
What are the pros and cons of getting the benefits at full retirement age or at age 62?
the advantage of taking your benefits before full retirement age is that you collect benefits for a longer period of time, the disadvantage is that your benefit is reduced.
Is there a way that I can know what would be the reduced amount I'd receive if I retire early?
