RetireBy90
Thinks s/he gets paid by the post
If you both do not die simultaneously, then one of you will have to live on the higher SSA benefit. Would delaying longer, even to age 70, make that a more comfortable situation?
If SSA is not a significant portion of your retirement spending plan, it may not matter.
This is the reason I’ll delay till 70, so DW has more “fixed” income if I go before she does. We live off pension and her SS at FRA and some investment income. I want to be sure she will be OK if I go early. Maybe not biggest payout from SS but it gives us a piece of mind.
