The ability to drop off to sleep is the cruelest unfair advantage on the planet. I have two sleep specialists, medication, and a precise routine I have to follow (not to mention charting the orbits of the planets, making a sacrifice of small children, and twisting my body into 190 pretzel positions) to suffer nights full of insomnia. While my husband rolls over and drops into instant dreamland.

But I have the steel-trap memory. So there’s balance. I don’t know that anyone gets all four advantages. Recognizing the ones you do can make you appreciate the positives in your life.

Even if you resent the sound sleepers of the world most of the time.
