As a massage therapist, my favorite past time is massaging myself. When I'm stuck in traffic, for example, instead of grumbling and stressing out, I try to use my time in a more helpful way. My favorite traffic massage is the neck press. (Keep your eyes on the road, mind you!) But it's just so simple and a great relief.
First: simply drop your right ear toward your right shoulder. This is a nice stretch all by itself. Then, press energy and peace into your neck with the heel (the part fleshy part of your palm closest to your wrist) of your right hand into the big muscle stretching from your ear to your collar bone on the left side of your neck. It's an easy muscle to find, especially if you have a life, a job, or children (or, in other words: stress). Press and release several times, increasing circulation and undoing tension. Be sure to repeat on the other side. And always remember to breathe when you massage!
