I think downsizing when you retire might be reasonable. Enough room for visits by kids and grandkids but not huge rooms for each kid like when they were 12 or 15. The china you have been saving to give to your daughters, they don't want it. Nor half the other stuff your saving for them. People moving from a house with a basement to one with only a crawlspace are in trouble unless they downsize the stuff they bring to the new house. (Except you cannot downsize your tool boxes of course).
