Strangely, I woke up thinking about sleep. Particularly, I thought of how people often say, "I don't sleep much, but I lie in bed and rest." Then I thought to myself:

Lying in bed, resting, and feeling it's the same as actually sleeping is like lying on the couch, thinking of exercising, and feeling it's the same as actually exercising.

Get your sleep, people. And, ironically, exercising helps with sleep.
