You walk past the vending machine at work and see that it has Zingers, snack cakes you haven't eaten in decades. It becomes disconcerting when you go back to your desk and discuss life and death matters with clients, all the while thinking, "10 Zingers, 9 Zingers, 8--Yummy!--Zingers, 7 Zingers, 6 Zingers, 5--Tasty..."
While the thought of the Zingers TV commercial jingle amuses you, you think, "I saw the Zingers commercial originally in 1980. I have a good memory, but I know I've forgotten more important things than this jingle. I haven't eaten or even seen Zingers snack cakes anywhere in many years. Why do I have instant recall of this jingle and not my blood type?"
The mind's priorities are sometimes disturbing.
