Dozing Hamster Takes a Tumble
It's 3 o'clock. You had a heavy lunch, and now you're getting that drowsy feeling at your desk that you feel every day around this time. You're putting more work into keeping your eyes from closing and your head from nodding than you're putting into your actual work.
Just be thankful that your desk isn't several feet off the ground. Then those afternoon drowsies could suddenly become a matter of life and death, or at least a matter of injury.
