Three older ladies were discussing the travails of getting older.

One said, “Sometimes I catch myself with a jar of mayonnaise in my hand in front of the refrigerator and I can’t remember whether I need to put it away or start making a sandwich.”

The second lady chimed in, “Yes, sometimes I find myself on the landing of the stairs and I can’t remember whether I was on my way up or on my way down.”

The third one responded, “Well, I’m glad I don’t have that problem – knock on wood.” She rapped her knuckles on the table and said, “That must be the door. I’ll get it.”
