This makes perfect sense to me. I knew I was getting old when I started uttering the phrase, "But I don't feel any different!" Which is what my mother used to say to me when I told her she was old.

A much younger co-worker said to me that she basically still thinks it's 2005, and I said I basically still think it's 1998. I realized that we both basically think it's the year we were 19-20.
