You're too old when?

your kids keep telling you to turn it down.

lol, When my husband’s grandma was in a nursing home, we went to visit her.  She lost most of her hearing.  She told my husband her stereo didn’t work, so my husband turned it on and said it worked just fine.  The nurse screamed “No, we only told her it didn’t work because she can’t hear and she turns it all the way up!”  He totally ruined their peace and quiet.

You reach your expiration date. 

You yell, "Get off my lawn!"

... you think you are. 

When the only females that find me attractive are mosquitoes.

You're never too old. There's just too many other people too damn young.

the only thing to look forward to when waking up is going back to bed.

Body Popping is no longer a dance move.
Your own flatulence takes you by surprise.

Your back goes out more often than you do.

Your broad mind and narrow waist trade places.

You look at a pretty girl and decide you're too tired. (If you don't even look, it's time to bury you - you've failed to notice that you're dead).

Your partner asks if you're interested in having super sex and you ask what kind of soup.

Your gray nose and ear hairs grow an inch a day.

You add "whippersnapper" to your vocabulary.
