There's no doubt that this is true, but I find that my wife has a lot better overall social life than I do, and she seems to keep busy and happy enough.

I think there's a good chance that she'll outlive me, and at least now I know for certain that she's well equipped to do that, as she's had a lot of months of living alone and having to do just everything. Perhaps my bigger worry is whether she secretly prefers it when I'm gone! (I'm sure there are days ...) :-)
