**Enhancing Learning and Sleep Spindles**

Walker discusses the importance of sleep for learning and memory. He argues that sleep helps to consolidate memories and to transfer them from short-term memory to long-term memory.

Walker also discusses the role of sleep spindles in learning and memory. Sleep spindles are bursts of electrical activity that occur during non-rapid eye movement (NREM) sleep. Walker argues that sleep spindles help to strengthen memories and to make them more resistant to forgetting.

He argues that sleep divorce can help couples to get more sleep, and that it can also help to reduce conflict between couples.
