At some point late in any afternoon, a 20 minute nap is restorative. It is a break and adds a little recharge to be ready to attack the rest of the day.
On a quiet weekend day, napping plays a different role. It fits neatly with other types of relaxation like reading a book, watching a movie. It's not about that extra boost of energy.
I propose that at least four naps a week should be legally required.
Anyone else with me?
