I had a recent lesson in hoarding! My father in law passed away, leaving my wife and I as the only living relatives. He had a house he built in 1958 and I do not think he ever threw out "anything that may come in handy sometime" It has taken us close to 3 months of working on it after work and on weekends to get rid of all the stuff. The Salvation Army has had 3 removal trucks full of donated goods from us, we have sold some furniture and I have taken just under 6 tonns of "stuff" to the dump. It ,of course, was even harder for my wife as lots of the stuff bought back memories of her childhood and her lovely parents.
It is finally finished and I can't tell you how glad I am to have that burden off my back.
So if you are getting on a bit and do not want to leave a nightmare job for your loved ones, get rid of all that stuff that is really just junk now, while you still can!
All the best.
Mike
