I’ve got a good decade and a half (or more) before I can be classified “a senior citizen”

Don’t fool yourself, Old Man. Those “senior menus” now start at 55!  🙂

What’s even scarier  is that you’re eligible for AARP membership at 50!
 
My rule of thumb is based on the following
1- if John Lennon has always been dead then you’re a pup
2- if you remember Jack Kennedy being alive then you’re “a little long in the tooth”
