Dr. Mitchell: Your daughter's problem is puzzling. Uncontrollable muscle shaking can be caused by several things, including neurological problems, muscle problems, metabolic problems (such as salt depletion, abnormally low blood sugar or dehydration) or even muscle exhaustion from overuse or overtraining. Take her to see her doctor. You may need to change your daughter's exercise program to avoid continued episodes.

George Foreman on ditching that double chin
A lot of readers have asked me whether you can exercise away a double chin. You can't "spot-reduce," but it can't hurt that old chin to give your neck muscles a workout. Use the four-way neck machine at the gym, or try this at home: Lie on your back, with a pillow under you to keep your shoulders off the floor, and rotate your neck from left to right and up and down. Then switch over to your stomach and repeat. Most double chins are just extra fat. When it comes to meat, follow the "if it doesn't swim or fly, don't eat it" rule. You won't get rid of that double chin by chewing on a steak.
