Assume that you only have the resources and money that you’ve acquired up to this point in your life, and you still have to pay rent, bills etc. You are basically physically capable of everyday activities but extreme feats (eg running marathons, climbing everest) are not realistic.
Holy shit, that sounds like you spend a lot of time thinking about that. First of all your relationship sounds like a dream. Hope it holds forever. I definitely got a lot of inspiration from your post, even tho I’m not looking the reaper in the eyes. Lots of good points how to plan our passing for the remaining people. Death can always happen to anyone unexpectedly. Always good being prepared. And I guess those are some good steps. Spending time with your loved ones is obviously important even if you are not the person facing death but if it is an elderly person.
