TEACH!
Teach . Teach someone. Teach someone something. Teach someone something that you already know and know about.
Might be a song. A poem. Or a recipe. Changing the motor oil. Potty-training a child. Building a house. Making a cake, or pies. Cleaning chitterlings. Whatever else it may be, that you already, know, teach another. Teaching them perpetuates your memory, and enriches the texture of living.
