Not to be doom and gloom (hah!)... and besides the obvious that you and your spouse love and belong together, does your spouse know the simple things like the following:

Bank account and other financial information...?
Where's the family safe? the key/combination?
What things come in the mail are important? unimportant?

This came up yesterday because my DH was looking for his own social security card and I told him it's in the safe... He didn't know where the key was and then he started looking for the safe. Whoa.

Is your spouse well-informed or will s/he have a bit of trouble if/when you bite the dust!??
