Why not retire at 62! No guarantee you will live to reach an older age so retire early and have some fun!

I at 66 still work 2 days a week...I decided to put in for SS at 65 and 1/2...they deduct a lot if you are still working but now, I'm getting my SS and my paycheck with no deducts.....and its coming in very handy to have all they extra income...
