I’ve come up with a few clues that might suggest teetering on the edge:
1.You've started keeping a thermometer on your bedside table and have actually googled the cost of a portable blood pressure machine.
2.Someone accused you of having a workplace like "Fibber McGee's closet" and you recognized the reference.
3.You constantly ask your grandchildren to explain words you don't understand.
4. You drove past a country churchyard last week and thought to yourself, "That would be a lovely spot for a headstone."
5 You started buying shoes without laces more often than not, because the floor has moved farther away than it used to be.
6. You worry less about forgetting where you put things than about people finding out you forgot where you put things.
7. When you used to watch scary movies, the vampires were the bad guys.
