Redditor u/Pred1949 asked the AskReddit community what made them feel old, and people responded with a wide variety of "I'm ancient" moments. Some of the best include not recognizing any of the bands on the Billboard No. 1 singles list, realizing that the song "1979" by The Smashing Pumpkins is closer to the year 1979 than it is to our current time, and having to help a young Walgreens clerk use a digital camera.
