Something I have that is the oldest that I still use is a very heavy and antique dresser that is just too heavy to remove even if I wanted to. I have the drawers full and the mirror is still attached. It is still in nice condition, too. The only reason I keep it is because it is too much of a hassle to get out of the house. I'm not even sure how it got in there, just that it's been there for about 33 years! It belonged to my grandmother's sister who was my Aunt. It was one of the only things I inherited from her so I could never get rid of it up til this point. I don't know how much it is worth if anything, but being it's such an antique I guess I would have to ask an antique dealer. What is the oldest thing you own that is still in use by you?
