 Yeah. Well, first of all, a lot of people don't realize this, especially if you're younger and you haven't thought much about this. But while both spouses are living, there could be a benefit paid on the higher incomes work record to the spouse who's still alive. So we have what's called spousal benefits, which we don't have under the federal retirement system. So in other words, let's say you had a spouse who worked very little outside the home, doesn't have much, if any, social security of their own.
