I used to work at a community college, where I was a TV/Radio Technician, and we had four types of students.
1. Teenagers who treated it like it was the 13th Grade.
2. 20-Somethings who realized they fucked up and were going back to school to turn their life around.
3. People in their 30s, 40s, or 50s, who had to change careers for whatever reason, and had to get back into the swing of things.
4. Senior Citizens & Retirees who were looking for something to do or to keep their mind active.
No, I haven't seen
Community. I worked at the college from 2007 to 2011 and, at the time, watching it would've felt too much like work.
When I was in college (as a student), every class always had at least one middle-aged student. And when I was hanging out with my friends, we had this one area where we all got together, and we had this one guy in his 40s who hung out with us, and we called him "Midlife-Crisis John"! Now that I think about it, I'm almost the age he was back then. Time is a horrible thing.
