So went on my tour of Brooklyn today, and as was previously mentioned in this thread, I look rather young. So I'm there in 21 Jump Street mode as usual, and the 3L tour guide starts talking about how surprised he was to learn of Brooklyn's older median age - "I had no idea that there would be so many older students at Brooklyn, I was really surprised to learn a lot of people came in after time in the workforce. The average age is like 23-24!"
At which point I had to contain myself from laughing. Was a wonderful tour though, the guide was great overall, and most importantly, he had a job lined up after graduation!
