If as a young man you get married, and on your honeymoon you purchase a large jar and on your wedding night for each time that you and your beloved wife make love you drop a penny into that jar. Then for the first year you remain married you continue to drop a penny into the jar until the day of your first anniversary.
After your first anniversary the next time you and your wife make love you REMOVE a penny and each time after that, each time you make love you remove a penny henceforth. Continue thus as long as you both shall remain together. Then.
You will NEVER empty that jar!
