"The task is so onerous that a new profession, called senior move managers, has arisen to help retirees sort their way through their mountains of possessions, one of many new industries in today’s longevity economy."

"Senior move managers exist for good reason: Without help, we may find that moving simply falls into the too-hard category, especially in later older age.... All of us live in many homes throughout our lives, but for many of us, the home of greatest significance is the one in which we spend our midlives, cultivating marriages, paying off mortgages, accumulating memories, raising children, progressing in our careers, and amassing possessions. Many, if not most, older adults have lived in the same residence for decades. After so much time spent in the same place, our memories are transferred onto the objects and environment around us. The architecture of our homes becomes part of the architecture of our minds. If we find ourselves restless at night, we can put ourselves to sleep just by performing a slow mental survey of every room in the house (try it, if you’re ever feeling insomniac). For those in later older age, in their 80s and 90s, a sudden unexpected move out of a long-lived residence can have a devastating effect on mental and physical health. Those of us with stronger constitutions might not crumble to dust, but still the experience is serious, natural doubts at the prospect of moving on from our longtime home. 'Am I really doing this? Am I really giving up my castle?'"

From "Want To Downsize In Retirement? Problem One, Millennials Don't Want Your Stuff" (Forbes).

What if all your memories could be saved? You've filled your head with that stuff. It's so important to you. But if, as you must leave this world, it could all be saved, would anyone want it? What are your favorite memories? What you could give them away, lodge them in someone else's head, where that other person could look upon them as if they were memories they acquired naturally — see "We Can Remember It for You Wholesale" by Philip K. Dick (AKA "Total Recall") — would anyone want them?

No, there are some things of yours that are great to you only because they are yours. Without you, they are worse than nothing, so it's best to let them go entirely. Let them become nothing, and not junky clutter for other people to hate.
