 We're seeing almost a doubling in those benefits if they're able to delay those out to age 70. And over their lifetime, that's adding about $350,000 in additional benefits.

And one of the key reasons that that is happening is if something happens to one of the two of you as you're on Social Security, the survivor is going to be left with a larger of those two benefits.
