I liked this handy tip that I found in an article called, The Art of Aging by Sparrow published in The Sun:

Napping is an art, like ceramics. A great nap can reinvent a day. You awake to clearer, fresher air - happier air. And old people are allowed to nap. In fact, it's considered a virtue.

I liked it because they mention ceramics. I have always hated naps - mostly the waking up part. Obviously I need to practice the art of napping!
