'OLD' IS WHEN... Your sweetie says, 'Let's go upstairs and make love,' and you answer,  
'Pick one; I can't do both!' 
 'OLD' IS WHEN... Your friends compliment you on your new alligator shoes and you're barefoot. 
'OLD' IS WHEN... A sexy babe catches your fancy and your pacemaker opens the garage door, 
 'OLD' IS WHEN... Going bra less pulls all the wrinkles out of your face. 
 'OLD' IS WHEN... You don't care where your spouse goes, just as long as you don't have to go along. 
 'OLD' IS WHEN... You are cautioned to slow down by the doctor instead of by the police 
'OLD' IS WHEN... 'Getting a little action' means you don't need to take any fiber today. 
'OLD' IS WHEN... 'Getting lucky' means you find your car in the parking lot.
 'OLD' IS WHEN... An 'all nighter' means not getting up to use the bathroom. 
AND 
 'OLD' IS WHEN... You are not sure these are jokes?  

Old is when you yell for your kids and have to run through ALL there bnames before hitting the right one.

Add some more yourself,

Old is when....your turn
