Ages 7,6,4,and almost one. I also have a couple of goldfish, ages unknown to me. My goldfish swim idly in circles all day long. They never get bored, they snack contentedly on the rotting food left over on the bottom of the tank. For goldfish, every lap is new and exciting.
Every turn is one they never made before.
That same old view is always new and exciting to them. Laugh if you must, but you haven't gotten to the funny part yet. My children must really relate to those goldfish. I know this because they, too forget almost everything they know almost every second. Take my next to youngest son, for example.
