When do we get old

Just got home from the ZZ/Cheap trick show. That was pretty Good! Cheap Trick kinda over drove the audio and the licks were drowned a bit but still performed well and the 5 neck hit the stage on the last song! ZZ fully took the roof off though! Those three guys are absolutely amazing!!
Last month the little woman and I saw the Doobie Brothers and Santana at the Sprint center in Kansas City. The Doobie's were great but Santana was unreal, 72 years old and still rock'n. The man played Woodstock, how cool is that!
