Lori B! sent this. . .Musicains know you're too old to gig when:
 1. It becomes more important to find a place on stage for your box fan than your amp.  2. You refuse to play out of tune  3. Your gig clothes make you look like George Burns out for a round of golf.  4. Your fans have left by 10:30 pm.  5. All you want from groupies is a foot massage.  6. Your after show party is at the International House of Pancakes.  7. You love taking the elevator because you can sing along to most of
your playlist.  8. You hire band members for their values instead of their talent.  9. Instead of a fifth member your band wants to spring for a roadie. 10. You lost the directions to the gig. 11. You need your  glasses to see the amp settings. 12. You've thrown out your back jumping off the stage. 13. The waitress is your daughter/grandaughter. 14. You stop the set because your pain killers fell behind the speakers. 15. Most of your crowd just sways in their seats. 16. You find your drink tokens from last month's gig in your guitar case. 17. You no longer use a tip jar. 18. You refuse to play without earplugs. 19. You ask the club owner if you can start at 7:00 instead of 9:00. 20. You check the TV schedule before booking a gig. 21. Your gig stool has a back. 22. You related to at least one member in the band. 23. You don't let any one sit in. 24. You need a nap before the gig. 25. After the third set you bug the club owner to let you quit early. 26. During the breaks you now go to the van to lay down. 27. You prefer a music stand with a light. 28. You don't recover until Tuesday afternoon. 29. You can't operate  without a set list. 30. You have a contract. 31. You hope the host's speech lasts forever.....

You buy amps considering their weight not their tone or cool factor. You feel guilty looking at the hot chicks at the bar because they're younger than your daughter. You can remember 7 different club names of the same location ... You have a hazy memory of the days when you could work 10 gigs in 7days *and* could physically do it.
