Oh yes, do keep old shopping lists etc, I kept my Grocery order book from when I first married and it was amazing how cheap everything was. I kept a lot of historical stuff, like ration books from the war, my Dad's war correspondant pass book etc, these came in so useful when we were teaching WW2 at school.But I always destroyed bank statements after say 5 years. Stuff that is of no interest or use I would ditch. I am a hoarder of interesting stuff and of books (oh dear me, that is reaching crisis point)
