This topic comes up here regularly, and I will say, as I have before, that I'm not going to, in my mid 50's, scale back things I enjoy and use, to a bare minimum, just on the chance I might die before I'm old.
I keep my papers in order and cleaned out. I don't keep anything broken or junky. When I'm done with something (say scrap booking or collecting/reading books on a particular subject), the 'stuff' goes out of the house. I've taken pictures of family heirlooms, and on the back written their history, and made a small photo album of them, so when I'm gone, my son won't have to guess what might be historical or not. He can choose to keep or get rid of anything he wishes.
There are auction services and estate sale services that will do all the work for people, so no one has to spend weeks or months cleaning out a relatives home if they really don't want to.
I want to continue to purge or keep what makes me happy and what I enjoy and feel is manageable and comfortable to me. I don't plan on making those left behind miserable by junking up on purpose (yep, some people do that). But if I had something like the photo albums the article mentioned, that brought me joy to review regularly of my travels and people in my life, I'm not going to feel guilt if my kid has to throw one or two on the burn pile when I'm gone.
With all the services out there, people don't have to be so inconvenienced in dealing with these kinds of things, if they don't want to or if it is too much for them to handle. Paring down as one ages, or at least keeping one's things in order and organized is a kind and helpful thing to do.
But paring down to almost nothing and denying oneself the things that bring them joy isn't anything I expect or want my mom to do, even at 82. I want her to enjoy the things she has worked a lifetime to have, and I want to do the same. I want her to let go of things that she no longer finds value in, or things that become burdensome to her, and I do the same. There has to be some kind of balance here, but unloading most of what one owns, just to lighten the load on one's family after passing, isn't really what will make for a full later life for many people. Can't take the stuff with you, but what one does love should be enjoyed as long as it brings joy.
