Found three old bottles of my own last year when I was cleaning out the bathroom closet, and two of them still had pills inside (which I did not expect at all). My doctor had switched me to something else and I just shoved the old ones in there and forgot about them for like two years. What got me was how the labels had different dates, so I could see exactly when my back went bad and when it got better and then bad again. My wife wanted me to flush them but I took them to the pharmacy drop box instead, and the guy there said people bring in stuff from like 2009 all the time. It made me wonder how many homes are just sitting on little time capsules of old pain. Your mom probably has no idea what half that stuff was even for anymore.
