When did I get old?

Really. It's a question I've been asking myself lately. Up until about 4 months ago, I considered myself young. Last night as I was getting ready for bed at 8:30, I realized that those times of staying up all night (or even 11) are over. I can barely keep my eyes open past 10 half of the time. Next thing you know I'll be playing pinocle and wearing black socks with my sandals. Now if you'll excuse me, it's time for my nap!
