Whilst not being morbid, it is actually a good thing to be prepared for the inevitable, eg to have made a will, gathered documents and important information together, let family know your wishes. And preferably, not leave too much chaos for the family to deal with. Declutter a bit.
Also for both spouses to be able to take up the reins of the household, as it is likely that one will die first.
I have quite a thing about this actually. I was once asked to help an elderly lady with finances after her husband died. She hadn’t a clue where to start. Her husband had always felt it was his role to deal with household bills.
Once things are in place, it is good to make the most of each day we have.
I would love to know my grandchildren are settled and happy, but beyond that, no I don’t worry about what I will miss.
