say You are old and married, but your H gets old and sick and dies first? Then you get sick? What do you do? Go out and find another old and sick man to take care of you?
You have 3 kids. They won’t let you just die. And you should absolutely be preparing for your old age. I work with old sick people. Some who are married, some who are widowed, etc. even the ones who are married, the emergency contact are the kids, grandkids, etc. and I can tell you, preparing properly when you are younger will save your a lot of trouble.
And you are certainly in no place for another R if you could see all of that happening. That shouldn’t even be on your radar now. Getting healthy should be your absolute number one focus .
