Interesting. I view the gambling the opposite way. If you take it early, you are gambling that you aren't going to live a long life where the larger benefits will be more useful, especially if you drain other resources. If I wait to collect but die early, I haven't really lose any bet because I didn't run out of money.
Put another way, my goal is to try to insure I have enough money to live comfortably no matter what age I die, rather than make sure I optimized the benefits for likely departure dates. If I wait to collect but die early, I won't have "beat the system", but I certainly will have had enough money during those few years so it won't bother me. Unless you know when you are going to die, it makes more sense to me to make sure you are covered for all ages rather than trying to squeeze more money out in an early death.
This. Times 10. Far better to delay taking SS early ( as long as you don't really need it) than taking it early only to find that you live a long life and are in danger of running out of money. Better to leave money on the table than be broke at age 90. Some may argue that by taking SS early, one's portfolio can continue to grow. But what if you DO take SS early and at the same time we have a devastating long term bear market. Then your portfolio takes a huge hit AND you have a smaller SS benefit.
Your SS is a guaranteed annuity from Uncle SAm. Sure....they may cut benefits, delay COLA's , etc. but for most of us at or near retirement age SS will always be there.
