I am still a decent distance away from considering myself ‘old’. I turned 32 last week, I don’t get confused by modern technology, I get very few eye-rolls when I reference popular culture around my students. My five month old daughter definitely makes me feel youthful, if a little tired sometimes.
Nevertheless, from time to time, I experience events that give me the sense that I am old, or at the very least getting noticeably older. This happens to us all in various ways. You might hear yourself saying things your parents exclaimed when you were little, or react to what you see on the TV with the disgruntled attitude of a person past their youth.
