During most of the year I don't have time to take a siesta every day. During the summer, and especially in August a siesta is absolutely mandatory. And when I talk about a siesta in August I'm not talking about some anemic little 10-15 minutes of barely closing my eyes, I'm talking about siestas of 45 minutes or sometimes over an hour. The kind of nap that upon regaining consciousness you don't look at your watch, you have to check the calendar. It really is too hot to do much of anything else from 3:00 to after 5:00 so you may as well close the blinds on the windows and Z-out for a while. Don't forget to turn off your phone.
