I feel old whenever somebody references a early 90s player as if he were from ancient history. (I was at Michigan in the early 90s.)
I guess I don't do much to try to feel young. I am coming to realize that each age has its benefits and challenges. It's a trade off. IMHO, feeling young or old is a red herring. It's all about enjoying the positives of wherever it is that you are at in life.
If I can be pardoned for giving unsolicited words of "wisdom" - My advice (especially to young moms and dads) is to enjoy whatever phase you are in and don't wish time away. My wife and I were blessed with three daughters within 4.5 years. When they were little, there was so much work to do that I couldn't wait for them to be older. That was a mistake. Don't get me wrong - I don't want to go back to changing diapers at 3:00 a.m. I just wish I had enjoyed the ride a bit more.
