The old couple's secrets

I asked the old couple what secrets they could tell me about living long and well. At first they looked at each other and laughed, then he declared,

"Things are as they are. I know my wife and she knows me. We don't hide from each other. We don't ask each other lots of questions, we aren't anxious, running around all the time. Everything is open between us. We say our prayers and do our work. Most of the day I am outside, and she is inside, and when we unite, we enjoy our company, thanks be to God."
