Well, the health blog at the Times, features today the book, “Don’t Swallow Your Gum! Myths, Half-Truths and Outright Lies About Your Body and Health,” by Dr. Aaron E. Carroll and Dr. Rachel C. Vreeman. I’ve heard almost all of these and am guilty of spreading some of them myself; I’ve inserted my comments below in italics.
1. Cold weather makes you sick. In studies of cold transmission, people who are chilled are no more likely to get sick than those who were not. It may be that cold weather keeps people indoors, where germs are more likely to catch up with you.
Recently, I read that researchers were able to determine that the rhinovirus that causes the common cold reproduces and thrives more readily in colder and drier conditions, which would – in conjunction with the ‘enclosed spaces’ theory above – explain it’s frequency in winter and it’s rarity in southern hemisphere locations.
2. Green mucus indicates a sinus infection. The importance of mucus color is a medical myth even doctors believe, the authors say. “There is no evidence…that antibiotics shorten the duration of an illness when green snot is a symptom,” they write.
I’ve used this determinate for years to help me decide whether I need to go to the doctor or just ride out my cold.
3. You lose most of your body heat through your head. There is nothing special about the head and heat loss. You will lose heat through any uncovered body part.
I tell people this all. the. time. and I also use it as the reason why I don’t wear hats in the summer.
4. Milk makes you phlegmy. In a study of 330 patients, nearly two out of three believed milk increases phlegm production. But it’s not true. In one experiment, volunteers were infected with the cold virus, and some of them drank a lot of milk as well. The weight of the nasal secretions did not increase in those who drank more milk, nor was it associated with cough or congestion.
As someone who used to sing and act, many people over the years have advised me to avoid milk and dairy products before a performance. On the other side of the coin, however: if you’re sick, sucking on a lemon immediately before your performance will do wonders.
5. Cracking your knuckles will cause arthritis. Knuckle-crackers are no more likely to have arthritis than those who don’t make annoying popping sounds with their fingers.
6. Birth control pills don’t work as well with antibiotics. A review of the literature concluded that common antibiotics don’t affect birth control pills. “It is much more important to take your birth control pill every day at the same time than to spend time worrying about your antibiotics,” the authors write.
7. Singles have better sex lives than married people. You may think your bachelor friends are having all the fun, but single people also go through a lot of dry spells when they aren’t dating anyone. The result — married people typically have more sex in a given year than single people. In one survey, 43 percent of married men reported having sex two to three times per week, compared to only 26 percent of single men. The numbers were slightly lower but similar for women. Married people are also more likely to have orgasms and give and receive oral sex.
8. Sugar makes kids hyper. Numerous studies show sugar doesn’t affect behavior, but most parents don’t believe this. In one study, parents were told their kids had sugar and they were more likely to report problem behavior — but in reality, the kids had consumed a sugar-free drink.
9. You should poop at least once a day. A half-truth, say the authors. Regular bowel movements prevent discomfort and constipation, but a perfectly healthy person may not move their bowels every day. Constipation is defined as having fewer than three stools per week.
10. It’s okay to double dip in the chip dip. In one study, scientists took a bite of cracker and then dipped it into salsa, cheese dip, chocolate syrup and water. They did the same test with a fresh, unbitten cracker. Then they measured bacteria in the dips and the volunteers’ mouths. On average, three to six double dips transferred about 10,000 bacteria from the eater’s mouth to the dip. And each cracker picked up between one and two grams of dip. Salsa picked up the most germs from double dipping.
11. Food quickly picked up from the floor is safe to eat. Scientists have put the commonly-cited five-second rule to the test. They found that food that comes into contact with a tile or wood floor does pick up large amounts of bacteria. Food doesn’t pick up many germs when it hits carpet, but it does pick up carpet fuzz.
To add to the list? Eight glasses of water a day, which science A) has no clue to the origin and B) pretty universally disagrees with.

If “The Hurt Locker” is not the best action movie of the summer, I’ll blow up my car. The movie is a viscerally exciting, adrenaline-soaked tour de force of suspense and surprise, full of explosions and hectic scenes of combat, but it blows a hole in the condescending assumption that such effects are just empty spectacle or mindless noise. [Director Kathryn] Bigelow … has an almost uncanny understanding of the circuitry that connects eyes, ears, nerves and brain. She is one of the few directors for whom action-movie-making and the cinema of ideas are synonymous.

“The Hurt Locker” opens today in NY and LA; July 10 nationwide.
Speechless and so sad. Rest in peace, Michael, you were a god among men.
For example, the debut of the moonwalk. No over-sized set pieces. No projection screens. No pyrotechnics. No backup dancers. And it’s completely and utterly engrossing:
