I ran some numbers of my own and made a few assumptions.
I'm going to compare drawing at 62 vs.70. By drawing early, I will have reclaimed $196,800.00 by the time I'm 70 years old. If I save it and invest it at 5% I will tack on another $20,000. If I wait till I'm 70 to draw Social Security, I will be 91 years old before I start to get ahead of the game. But this isn't the BIG issue!
Social Security is a big investment. And you have a partner who manages your savings for you. And your investment partner is a psychotic, crack addict with big spending problems! How long do I want Uncle Sam holding onto my money?
