Busy roads and drowsy drivings make summer roads especially dangerous.If you're hitting the road for your summer vacation this year, one thing you'll need to contend with is dangerous drivers. From tailgaters to clueless motorists who don't use signals to texting teens, being alert on the road is more important than ever. And yet many of us aren't as alert as we should be. This was brought home recently in a tragic accident on Cape Cod, Mass., in which a recent Yale University graduate was killed in the middle of the afternoon when her boyfriend fell asleep at the wheel.

4 tips for safe summer travel

As it turns out, drowsy driving is more common than you think. According to the most recent statistics from the National Highway Traffic Safety Administration, approximately 100,000 police-reported crashes are the direct result of driver fatigue, causing 1,550 deaths and 71,000 injuries each year.

Perhaps the most surprising of the study's findings is that most fatigue-related accidents or near-accidents occur during daytime hours when roads

Iced tea is a great anti-aging summertime drink.Sure, you've heard all about New York City Mayor Michael Bloomberg's plan to ban supersize sugary drinks. But we'll bet you're not cooling off this summer with Big Gulps of Mountain Dew anyway. Here's some good news: Iced tea -- that beloved summertime sipper -- has some awesome anti-aging benefits. Any type of brew will do.

Green Tea
If you want to whittle your waist this summer, pour a nice, tall glass of iced green tea. Researchers say the tea's caffeine and antioxidants called catechins help rev up the body's metabolism to melt belly fat. Some research suggests catechins also help curb appetite. You'll need to sip a lot, though -- roughly 7 cups a day -- to reap this benefit. But all that green tea is good for your brain, too. It contains the amino acid theanine, which helps fine-tune mental focus.

White Tea
Want to look younger this summer? Make a pitcher of iced white tea. It has anti-aging anti-inflammatory

Want to grow younger in 2012? Pump iron a few times a week.We all know what can happen as we get older: memory loss, aching bones, low libido, heart disease, diabetes . . . But the real culprits aren't the problems per se, but the biological mechanisms that cause them in the first place. Here are 10 major agers -- and what you can do to fight back and stay young.

1. Major Ager: Bad Genes and Short Telomeres
Responsible for: Memory Problems
Your genes are key in determining how you age -- and which conditions and diseases you're most vulnerable to getting. It's true, you can't change your genes, but you can help control the way they're expressed. How? Take telomeres -- the tips of your chromosomes. They're much like the tips of a shoelace, and with general wear and tear, they can shorten and fray, causing age-related health issues, such as memory loss.
Action Plan: Help keep your telomeres -- and memory -- sharp with stress reduction, brain games, and regular exercise.

Don't let someone else's chronic whining get you down.By Julie Hanks, LCSW, for Sharecare

Whining children are difficult to tolerate, but whining adults can be even more challenging! Unlike your children, you can't send your neighbor, co-worker, or best friend to their room when they start sulking or complaining incessantly. Unfortunately, we live in a culture where whining adults are tolerated and often even glamorized on reality TV shows. Somebody else's chronic negativity can drain the joy out of your relationship with him or her -- and zap your own emotional energy.

What being a good friend does for your health

I was recently interviewed for a story in The Wall Street Journal called "A Nation of Whiners: Therapists Try Tough Love." In it I talked about how I confront therapy clients who complain for weeks and months on end and help them get to their core problems. Chronic complaining isn't necessarily therapeutic or helpful in therapy -- or in relationships outside the therapy office.

Perimenopause symptoms can be subtle.By Deborah A. Wilburn

Hot flashes, vaginal dryness, irritability. These are all common signs of perimenopause -- the five- to 10-year period during which your estrogen levels fluctuate and egg production becomes erratic until your menstrual cycle stops completely. One year after your very last period, you're considered to be in menopause. The average woman enters menopause at age 52, so you could start developing symptoms anywhere from your early 40s to your late 50s.

Think you're in perimenopause? Why you still need birth control.

There are other perimenopause symptoms that many women overlook, says JoAnn Pinkerton, MD, ob/gyn professor and director of the Midlife Health Division at the University of Virginia. If any of these is familiar, you may be in perimenopause:

1. Your period stops for 3 to 6 months, then starts again. Some women may think they're pregnant, and when they turn out not to be, write it off as nothing in particular. But sporadic menstruation is a

Load up on watermelon to look younger this summer.Of course, you should slather on plenty of SPF 30+ sunscreen all summer long -- year-round, really -- to help prevent aging sun damage and skin cancer. But compounds in summer-fresh fruits and veggies also have anti-aging benefits to boost your skin's natural resilience against wrinkles and sun damage. Pick up these four goodies next time you're at the farmers' market:

• Cherries: Eat a daily handful and you may enjoy fresher, less puffy skin. It's all thanks to the inflammation-fighting anthocyanins and melatonin in cherries, according to Allison Tannis, author of Feed Your Skin, Starve Your Wrinkles. Melatonin may boost UV protection and cell growth as well -- two great ways to keep wrinkles at bay. Tart cherries tend to be highest in melatonin.
• Nectarines: These smooth-skinned sisters of the peach provide a mini-spa's worth of nutrients that may help correct sun damage from the inside out, according to Tannis. They offer skin

Forever 21 Skinny JeansI love my skinny jeans as much as the next woman, but now (along with high heels, flip-flops, and platform shoes) they come with with a potential health risk: A little problem called meralgia paresthetica. In plain English, it's a condition that causes "pain, tingling, burning sensations or numbness in an oval area over the front and side of the thigh," says Sharecare expert Darshan Shah, MD, a neurologist at NorthShore University HealthSystem.

When you wear skinny jeans, it can cause the artery inside your thigh and the nerve next to it to be squeezed together. As a result, says Mehmet Oz, MD, "the blood can't flow to the tissue, plus the nerve next to it gets irritated."

Not all vitamin D supplements are created equal.We're always urging people to get the nutrition they need from food rather than a pill. But there's one nutritional supplement we think just about everyone needs: vitamin D. Your body produces vitamin D from the sun (and you get some vitamin D from food), but if you're careful about using sunscreen every day (a smart idea to prevent skin cancer), chances are you to don't manufacture enough vitamin D, even in the summer.

Is your sunscreen safe?

That means you may be low on this anti-aging vitamin. Recent research links low vitamin D levels to everything from heart disease, diabetes, and osteoporosis to breast cancer and ovarian cancer.

"On the upside, researchers have found that having healthy amounts of vitamin D3 relaxes your blood vessels, helps bone-building drugs work better, and makes weight loss faster and easier," says Michael F. Roizen, cofounder of RealAge and chief wellness officer at the Cleveland Clinic.
