The Dangers of Texting and Walking

If you text while crossing the road, you might not make it to the other side. That’s because pedestrians who text or talk on their phones are less cautious and walk more slowly than undistracted walkers, according to a new study published in the journal Injury Prevention.

Researchers monitored 1,102 walkers at 20 different intersections in Seattle, Washington. They found that one out of every three people used their phones to talk, listen to music, or text while they crossed the street. On average, music listeners walked slightly faster than undistracted pedestrians, but texters took 18 percent longer to cross the street. Moreover, the texters were nearly four times more likely to disobey traffic signals, cross mid-intersection, or walk without looking both ways—an obvious recipe for disaster. Worse yet: Women were twice as likely as men to exhibit at least one unsafe crossing behavior.

Not surprisingly, previous studies have found that while people know it’s dangerous to walk or drive while using a phone, they continue to do it. No wonder the Centers for Disease Control estimate that 4,000 pedestrians are killed every year, and another 60,000 are injured.

One surefire way to enhance your roadside safety is to power down while you’re in transit. But if imminent danger alone doesn’t convince you to keep your phone in your pocket, maybe this will: it’s rude to talk or text while you walk. To minimize insult to injury, ask yourself these questions before you next use your phone on the go:

1. “Is someone walking behind me?”
When your eyes are on your screen, your feet move more slowly, and you’re more likely to collide with or hold up the person behind you. “Any time you are inconveniencing, slowing down, or nearly bumping into someone else as a result of an activity conducted for your own convenience, you are, in fact, being rude,” says Thomas Farley, author of Modern Manners: The Thinking Person’s Guide to Social Graces and the blog, What Manners Most. In crowded areas, find a side street that’s less congested before you text or talk.

2. “Can I express myself clearly right now?”
While you’re walking, your mind is more likely to be focused on your destination than the person you are communicating with. Not only can a thoughtless text misconstrue your message, but a text laced with typos shows you just don’t care, says Farley. Instead of pounding out of a message on the go, think about what you’d like to say while you walk, and write it out later.

3. “Should I call instead of text?”
While text messages are the perfect medium for sending brief notes (“C u there @ 6?”) it’s best to discuss complex matters on the phone, says Farley. Unlike writing a text message, making a phone call leaves your eyes free to focus on the road and other obstacles (like moving people). That said, don’t assume that your friend is free to talk whenever you are. Using the instructions above, send a quick text to ask if she has time to chat, and arrange to call her at a convenient time—ideally when you’re not in transit.

4. “Can I wait to make this call?”
Avoid phone conversations when you’re standing shoulder-to-shoulder with strangers; unless your news is relevant to all, your voice is an unwelcome distraction. If your call can wait–and most calls can, says Farley—but your message is urgent, text it instead: Veer away from pedestrian and road traffic. Then stop walking, and switch off your phone keyboard sounds, and text away.

The Dangers of Eating Canned Foods

bpa side effects: canned foodBy now, you’ve likely heard about the health effects of Bisphenol A (BPA), the plastic-hardening chemical used in canned food linings and in other consumer products too numerous to list. (It can have negative effects on the brain, behavior, and prostate glands and has been linked to increased risk of diabetes and cardiovascular disease.)

And maybe you stopped using plastic water bottles and eating canned food. But if you haven’t yet made a change, or your vigilance has lessened, listen up: A new study implicates BPA as negatively affecting the health of not just those who ate BPA-laden food but also of four generations of their children. Considering that BPA is found in 90 percent of Americans’ blood, that’s a lot of children who could potentially be impacted by an innocent-seeming can of spaghetti and meatballs.

The new study, published in the journal Endocrinology, examined the trans-generational effects of BPA on mice. The researchers fed BPA-laden food to one set of mouse mothers and regular food to another, then monitored the behavior of their pups and that of three subsequent generations. The scientists also submitted the animals to genetic testing.

The mice that were directly exposed to BPA in the womb were less social and more isolated than the other group. They spent less time exploring their cages and engaging with other mice. But by the third generation, the behavior had flipped. The BPA-exposed mice were more social and engaged than the other mice. While that may sound like a good thing, it isn’t. It simply means that the chemical continues to influence brain activity for generations, the authors wrote in their study.

In fact, some of the behavioral issues they saw in all generations of mice were similar to those seen in autistic children and children with attention-deficit hyperactivity disorder. “Autism is characterized by a reduction in social interactions and we observed some declines in social interaction in the BPA-exposed mice,” says Emilie F. Rissman, the study’s lead investigator and a professor of biochemistry and molecular genetics at the University of Virginia School of Medicine.

As for genetics, the researchers found in all four generations of BPA-exposed mice that the chemical changed how estrogen receptors were switched off and on. They also saw changes in the way that two other hormones acted in the mice’s brains—oxytocin, the “love hormone,” and vasopressin, which influences hostile behaviors and reactions to stress.

What was interesting—and disturbing—about this study was that the researchers exposed the mice to levels of BPA that humans would normally be exposed to in their diets. “Mouse behavior and human behavior are miles apart,” says Rissman. But because mouse and human genetics are so similar, the animals are a good laboratory model for what could be happening in people, she adds.

Here are the best ways to keep BPA out of body:

• Ditch canned food. Cans are lined with an epoxy resin that’s made with BPA, and that includes things like soup, canned beans, and soda. Look for aseptic cartons, glass jars, and frozen foods as alternatives.

• Swap to glass containers. Rather than store your leftovers in plastic tubs, use glass or ceramic containers and dishes. Stainless steel containers make great substitutes for plastic lunch bags and takeout clamshells.

• Don’t be duped by “BPA-free” plastics. A study in the journal Environmental Health Perspectives found that those seemingly better plastics can contain BPA alternatives that are even more harmful.

• Decline receipts. They’re coated with a BPA-based coating that rubs off onto your fingers and whatever else it comes in contact with.

• Be wary of dental sealants. BPA is the most commonly used dental sealant material, and it’s used in composite fillings used to treat dental cavities. A recent study linked BPA in dental treatments to social problems in children, as well, prompting pediatricians to call on dentists to find other materials. However, because BPA is the most durable protective alternative in many dentists’ toolboxes, they’re currently reluctant to use other materials (and considering that the other primary filling alternative is mercury, the alternatives can be just as bad). Preventing cavities and tooth decay is your best bet here: Brush regularly and visit your dentist for regular cleanings.
