A lot of people are familiar with the steady bounce of cardiopulmonary resuscitation (CPR) and its proscribed 100 chest compressions per minute. But many don't know that, done correctly, it almost exactly replicates the rhythm of the 103-beats-per minute disco classic "Stayin' Alive." (Oh, the delicious symbolism!)

According to a study, medical professionals who learned to measure their CPR tempo with the famous disco song kept almost perfect (and potentially life-saving) time when performing the procedure. So if you're tasked to perform CPR, sing the Bee Gees' hit softly to yourself, because it's the one time in your life people won't make fun of you for it.

Serendipitous? Or just a clever teaching tool? Probably a little bit of both. But we still say the American College of Emergency Physicians (at whose annual meeting the study will be presented) should recruit John Travolta. You know, just in case.

Also on Lemondrop ... While we're on the topic of heart-stopping, check out our favorite Hollywood heartbreakers.

Hot Bod Cold Heart

    Mario Lopez Who knew that A.C. Slater was such a dirtbag? The buff "Dancing with the Stars" stud reportedly cheated on one ex-girlfriend with a Hooters girl, and his two-week marriage to Ali Landry ended when she learned of his bachelor party antics.

    Jude Law He may be gorgeous (and who can resist that accent?) but not so hot was his cheating on then-fiancee Sienna Miller with the nanny to his kids. Miller and Law eventually broke up, and her downward rebound spiral led her into the arms of mangy Rhys Ifans.

    Sony

    Matt Damon Although he has denied it, Minnie Driver says she discovered she was dumped by watching "Oprah. Say what!? The "Sexiest Man Alive" told the talk show host he was no longer dating Driver; Driver claims it was the first she'd heard of their breakup.

    Universal

    Hugh Grant Who could forget the Hugh Grant scandal that rocked Hollywood in 1995? Grant was pulled over by LA police for lewd conduct with prostitute Divine Brown. Girlfriend Liz Hurley forgave him and even appeared on his arm at the premiere of "Nine Months" days after his arrest.

    David Beckham What is it with married celebrities and the hired help? Although he has always denied it (and ok, so there's no proof), Becks was accused in 2004 of sleeping with then-personal assistant Rebecca Loos.

    Milk Processor's of America

    Chace Crawford We know two things about the "Gossip Girl" boy: He's a total hottie, and he dumped Carrie Underwood via text. US Weekly reported in April 2008 that the pair "mutually" parted ways via cellular phones.

    Charlie Sheen Among other lowlights, Sheen 'accidentally' shot ex-fiancee Kelly Preston, spent thousands on madam Heidi Fleiss, and symbolically took a chainsaw to his wedding portrait with Denise Richards. Ew.

    Ethan Hawke We were sad enough when this brainy babe's artsy-smartsy marriage to Uma Thurman ended. But to then shack up and have a baby with the nanny to his kids with the hot blonde? For shame!
