This hobby can help you feel old fast.
Remember how hot those 1990 Leaf cards were when they came out? The kids that graduated high school this last June don't, because most of them weren't born yet.
Remember the first set you put together from packs? Mine was 1985 Topps, that'll be 25 years ago in a few months.
Remember the Topps sticker books and the 25 cent packs of stickers? That was almost 30 years ago now. I used to be able to name all 26 teams, their home stadiums and their pennant/WS wins.
