Stress

You know something's wrong when:

- your jaw is so tight from clenching that you can barely open it
- your knuckles are sore, creaky even
- you feel shooting pain in your back as each new knot begins to form
- you pop pain killers in vain hopes they'll relax you
- your friend, out of pity and alarm, starts demonstrating stretching exercises in the middle of a restaurant, over brunch
- in spite of all your efforts, 8 hours just isn't enough
