I used to have my secretary take all of my calls every day , and then I'd go in my office and turn off the lights , and kick back in my chair for an hour or so to refresh my brain.
Now at my new job , I've got no secretary , and no office of my own , so I go home at lunch ( 3-6 minute commute ) and take a 45 min nap.
I'm 30 years old I might add. And I love this rest time that I get.
