My parents admirably started serious decluttering from about age 70. They had moved a couple of times later in life, so that helped. As soon as my father realised he wasn't going into his workshop any more, and never would again (he made some really beautiful furniture), he sold the big woodworking tools to younger friends who he knew would treat and use them properly. My mother has always kept the office neat and tidy, having been a secretary all her life, and when my father died, she started getting rid of all the books and had the bookshelves taken down and the lounge repainted. Now she just has a couple of dictionaries and photo albums. Every time I visit her we go through another kitchen cupboard and use up or throw out cans and jars of food which have passed their sell by date.
A second freezer out in the garage was recently defrosted and decommissioned, but has yet to be thrown out or sold.
Having said that, she does have the plastic containers and the rubber bands. Next up will probably be the Tupperware cupboard.
