Shopping at the Feel Good Store is a kind of funny experience, because I feel like it should be called "Imgettingold.com." But, darn it, it's got some freakin' great products at kick-butt prices, and after the New York City Marathon, I learned from a few amateur runners that it's a life-saver.

Like Light Force Therapy, a device that uses LEDs to produce safe (UV and laser ray-free), low-level infrared light, which helps temporarily elevate muscle tissue temperature, increasing local blood circulation.

Each of these factors assist in relieving pain and relaxing muscles by providing soothing warmth for promoting temporary relief from minor muscle and joint pain, arthritis and muscle spasms. There are six user-controlled settings and a full cycle setting that rotates through all frequencies. There's a timer for Light Force Therapy's patented EPS (Ear, Palms and Soles) Routine, which tells the user when to change positions. Comes complete with instruction booklet, power adapter and strap kit for hands-free treatments. Weighs 1.5 lbs. Covers 20 square inches. FDA Approved.

You gotta admit, while it's no deep tissue massage, it's painless and easier to use than that old hot water bottle of yours. So run your marathons and do your workouts now, but keep it handy for when the arthritis sets in later on!
