What I learned from "The Boss"

I went to the Springsteen concert on Friday night.  I'm a fan.  I'm not a Springsteen fanatic like two of the guys I went with.  They knew every word of every song.  I faked like I knew all of the lyrics.  "Screen door slams, Mary's dress sways, like a vision she dances across the porch as the radio plays.  Mumble, mumble, and mumble, mumble, hey that's me and I want you only... Why did I pretend to know the words when I didn't?  Why do I care so much about my Springsteenaoke performance?  Was I just trying to keep up with The Fanatic?  I'll have to think about that one and get back to myself.  But, I can tell you I did learn a lot from Friday night.        Springsteen is 74.  I'm almost 60.  He played for 3 hours straight with no break.  I went to the bathroom 3 times and sat for about 30 minutes.  He's fit.  He's strong.  He's soulful well into his 70's.  Age is only a number....
