Most of what I have read is break even for 62 vs 70 age to start collecting SS is 83 years old, you live longer you should have waited from a purely financial perspective. Studies also show most would be best financially waiting until 70. Those suggesting 62 is best financially are probably using higher returns then would normally be gotten with age appropriate investing, it might work but there is risk.
That said most including myself don't want to work until 70. I could retire at 62 and be good but I feel like I should work a little longer just in case I want more extravagances in retirement or my kids are struggling I may want to help. I am thinking 63 - 65 range although the studies said that was the worst time to take SS, lol. I have friends in the 63 to 65 range and none have retired and they are not even talking about it.
Whenever you retire have a social plan set up, you will be getting 40 - 50 hours per week that you haven't had for the past 40 years. A relative of mine worked until 73 and really didn't need the money. He retired and said he noticed cocktail hour kept getting earlier each day. As a big golfer he took a job at a golf course driving a cart and emptying garbage to keep himself busy. I am a little ways off but plan to have a weekly schedule and to my best to keep it, biking, excercise, swimming, golfing, hobbies, traveling to away RU games, whatever. Don't sit still.
