If you see professional athletes or weekend warriors with a crazy crosshatch of tape on their shoulders, knees or elbows, they probably aren't making a fashion statement. Chances are they're trying to tape over some pain. So-called kinesiology tapes — two prominent examples are Kinesio Tex Tape and KT Tape — gained worldwide attention during the 2008 Olympics, largely thanks to the heavily taped shoulder of American beach volleyball player Kerri Walsh. Unlike traditional tapes that wrap around joints to provide support and compression, kinesiology tape sticks directly to the sore spots like big Band-Aids.

Botox is remarkably safe, especially considering it's a powerful toxin. Occasionally, a mild headache that lasts a few hours may occur after an injection in muscles of the forehead. Very rarely, though, that headache may become excruciating and can last as long as a month.

Fitness stores sell a variety of spinal decompression/traction devices -- inversion tables and ankle boots that hang you upside down and stretch out your back -- on the promise that they help relieve back pain, enhance general back fitness, provide deep relaxation and maybe even slow age-related height shrinkage. The last, after all, is partially caused by the flattening and dehydration of the soft disks that separate your vertebrae. Salespeople say that running, lifting weights, carrying excess pounds, even the simple act of sitting in a chair all day can exaggerate the compressive force of gravity on the disks, which tend to shrink as much as a half-inch during the day and, like sponges, rehydrate during sleep.

AS they seek to document and demystify one of life's great thrills, scientists have run across some real head-scratchers. How, for example, can they explain the fact that some men and women who are paralyzed and numb below the waist are able to have orgasms? How to explain the "orgasmic auras" that can descend at the onset of epileptic seizures -- sensations so pleasurable they prompt some patients to refuse antiseizure medication? And how on Earth to explain the case of the amputee who felt his orgasms centered in that missing foot?

Pain is private. Unlike blood pressure or temperature or other symptoms easily measured and defined, the physical reaction to unpleasant stimuli is hard to quantify or predict. It varies from person to person, with each individual describing pain — and its intensity — differently. But that private perception can make the difference between a trip to the medicine cabinet for an aspirin or a trip to the doctor's office for something much stronger. Researchers study pain not to separate whiners from stoics but to understand why pain varies and, eventually, create individually tailored treatments for the many specific ailments that fall under the umbrella of pain.

When a recent study found that a popular knee operation was only as good as a placebo for arthritis, some sufferers misconstrued the results, assuming that no surgery would help them. Doctors are now trying to reassure people this isn't the case.

Can "super-oxygenated" water make people run faster? Yes -- if they think it can. The water, marketed under different brands, is touted as having more oxygen content than regular tap water and, thus, the ability to enhance athletic performance -- claims that have been debunked by scientists who consider it no more than nicely packaged snake oil.

Dr. Louis Lasagna, 80, who led a crusade calling for the clinical testing of drugs before their approval and rewrote the Hippocratic Oath recited by graduating doctors, died of lymphoma Thursday in a hospital in Newton, Mass. Lasagna, a native of Queens, N.Y., who served as dean of Tufts University's Sackler School of Graduate Biomedical Sciences for two decades, was best known for his work in clinical pharmacology.

Regular exercise could help lift the cloud of major depression as effectively as an antidepressant, new research shows. "A lot of people know from their own experience that when they exercise, they feel better," says James A. Blumenthal, a professor of psychology at Duke University and lead author of the study. But such anecdotes and gut feelings don't amount to clinical proof.

If you want to eat to maximize your mood and brain power, here's what the experts recommend: ? Breakfast: Studies have provided good evidence that a healthy breakfast leads to better cognitive performance, especially in children. ? Enough calories: Few things make people grumpier than being calorie deprived. If you're hungry, anything with calories will help. ? Regular meals: Keeping your blood sugar even by eating regularly ? about every four hours ? will help keep your mood level all day. Conversely, skipping meals and eating erratically will lead to highs and lows.
