We always hear that the first year of marriage is hardest and getting married young often ends in divorce after just a few years (or months). And-be honest-it kinda leads you to think that if you make it past the 10-year mark, you're pretty much in the clear. Which is probably why it was so shocking to find out about two double-digit marriages falling apart this week. Mark-Paul Gosselaar and his wife of 14 years called it quits. And just recently, Al and Tipper Gore announced that their 40- (yes, four-zero) year marriage was over.

Relationship 101: What's the Best Age to Get Married? Here's What the Research Says...

It's hard not to feel a little shaken. Sure, we're used to reading about celebrity starter marriages biting the dust and women in their early 20s filing for divorce. But 40 years?! So, uh, are we never really "safe"?

Have a big date or party coming up and just a couple of days to prepare for it? We have shortcuts to looking head-to-toe spectacular.

1. If you'd rather not stick to a strict diet, simply eliminate simple carbs (white bread, rice, pasta) and sugar. Also, resist sprinkling salt on your meals - sodium causes you to retain water. Make sure you aren't eating one of these so-called healthy foods.

2. Drink at least four cups of water plus four cups of green tea (it's a great fat burner) each day. And nix alcohol, which is high in calories, slows down your metabolism, and makes a mockery of your willpower. No wonder it's one of the best weight-loss tips ever.

3. Get between seven and eight hours of sleep a night to give your body enough time to make those growth hormones. Even just a couple nights of good sleep will make a big difference.

4. The fastest way to fix puffy eyes or dark circles: Brew two green tea bags, and let them cool. Then lie down and place them over your

There's a little tweak you can make that is scientifically proven to let a guy know you're interested. And no, it's not batting your eyes, pulling your V-neck down an inch, or casually dropping that you've memorized the entire Cosmo Kama Sutra. Researchers just discovered that when a woman is attracted to a man, she lowers her voice, making it huskier and breathier. Are you a good flirt? Take this quiz to find out.

The scientists were surprised since women often try to seem more feminine when flirting, and the expectation would be that they raise their voice when talking to a cute guy. See the secret signals his face is sending you.

So if you want to send the message to someone that the conversation is more flirty than friendly, just bring the pitch of your voice down a bit. It'll let him know you're into him and get him in a more seductive mindset.

Are any other subtle signs you give off when you like a

Could using the dryers at nail salons-you know, the ones you stick your finger or toes under so you mani-pedi dries faster-lead to skin cancer? That's the buzz we've been hearing lately; that since the bulbs in these dryers emit UV light, they're practically as dangerous as indoor tanning.

So we checked in with dermatologist Ellen Marmur, MD, author of Simple Skin Beauty and chief of dermatologic surgery at Mount Sinai Medical Center, New York City. Dr. Marmur told us that our fears are warranted. "The dryers are definitely emitting UV light, yet it's hard to know how much because the machines aren't regulated," she said. "But it's very possible that putting your hands or feet under them is the equivalent of sticking them in a tanning bed for the same amount of time." And she adds that the older the machine, the more UV light is emitted. Find out what tanning salons aren't telling you.

Pretty terrifying stuff, especially since many of us get our nails done monthly or even

Here's how to tell if a bad friend might one day pull a b---- -move on you.

1. She only tags you in her Facebook pictures if your eyes are closed or your back is turned away from the camera. Time to unfriend.

2. When you tell her that you caught your boyfriend in bed with another woman her first question is, "Was she pretty?"

3. She barely speaks to her friends from high school and college, but her lawyer is on speed dial.

4. Her new cocktail ring looks mysteriously like the one you just misplaced.

I was waiting for a friend at a restaurant when a beautiful woman asked if she could join me. She sat down and said, "You don't remember me, do you, Matt?" She looked familiar, but before I could respond, she said, "It's Belinda, from Philadelphia." Um, Belinda (not her real name), as in the craziest ex-girlfriend ever? I scanned her body for hidden weapons. You see, even guys who race motorcycles and laugh at Saw VI want to run to Mama when faced with a psycho ex. Find out the 10 things guys never want to hear about your ex.

Sudden Amnesia

I thought I had blocked out the bad memories in the seven years since our split, but the flashbacks began immediately. There was Belinda threatening to jump out of the car if I didn't let her listen to my voice mail. Belinda accusing me of sleeping with the coworker I was having lunch with. And how could I forget Belinda parking outside my apartment and watching me walk by with another date? I was ripped back to reality when she said,

Whether you've missed a Pill (or two) or need to know what's up with your flow, our trusted docs answer your FAQs. Plus, find out if you're risking getting knocked up.

SOMETIMES I FORGET TO TAKE MY PILL. IS IT SAFE TO TAKE TWO THE NEXT DAY?

If you skip a Pill, get back on track by taking it as soon as you realize your mistake. Then take the next Pill at your usual time, even if it's simultaneously with the one you missed. By quickly resuming your normal schedule, you won't increase your odds of getting pregnant or wreak hormonal havoc on your system. However, if 24 hours have gone by - or you miss your Pill more than twice a month - your baby-making risk rises. So play it safe for the rest of your cycle by using backup birth control, like condoms.
