Subject: [CR]seatpost slide

What are the possible reasons for my seatpost sliding down slightly but definitely while riding? Never had this problem before -- but have been using the same post for 25+ years and the bike was service recently which included the seat/post being slid up and down several times.

Can a post wear out? What about the insides of the seat tube on a 25+ year old frame? Or is this most likely a binder bolt issue?
