The Science of Love
Correct Answer : True OK , so maybe not fully developed love , but a quick passionate response is possible . Your brain can release love-related chemicals in a split second after you spy someone you love . A 2010 study also showed that new love really is like a drug . It sparks the same euphoric feeling as cocaine -- in the same part of the brain .
Correct Answer : Your levels of serotonin go down Calvin Klein named a perfume for the early stage of love : Obsession . Italian scientists found a biological link between people with OCD -- a treatable type of obsessive thinking -- and those in love for less than six months . Both showed lower than normal levels of serotonin in their blood .
Correct Answer : All of the above When you ’ re love-struck , your brain is flooded with dopamine and norepinephrine , triggering euphoria . That ’ s why new lovers do things like talk all night , dote on little details about each other , or fly across the country for a weekend together . Falling in love also triggers adrenaline , which may make your heart race and your knees shake when you ’ re near your lover .
Correct Answer : Immune systems You would probably never think of smelling a guy ’ s sweaty T-shirt to see if he ’ s the one ! But researchers gave women this smell test -- and some were turned on by the sweat of men whose immune systems were different from their own .
If you ’ re looking for a mate this makes sense : Children who get several different disease-fighting genes may be less likely to get sick . But it may also affect romance : Women whose immune genes are similar to their partners ’ may be more likely to be unfaithful .
Correct Answer : True Confirmed bachelors beware : In some studies , men preferred the odor of T-shirts worn by women while they were ovulating . And a study done in men ’ s clubs showed that men tipped lap dancers who were ovulating almost twice what they tipped dancers who were menstruating .
Correct Answer : All of the above No wonder George Clooney is such a heartthrob ! There may be a biological reason why ovulating women prefer men with strong jaws and cheekbones : They are signs of testosterone , which signals good health . And a sense of humor may be a sign of intelligence , another plus when procreating . Research also shows that women prefer more feminine male faces at other times of the month . A softer face may suggest commitment and good parenting skills .
Correct Answer : Testosterone Testosterone -- in men and women -- is the only substance known to arouse sexual desire . Oysters have high levels of dopamine , but there ’ s no proof that eating them boosts your libido . And chocolate has high levels of phenylethylamine
( PEA ) -- the “ love molecule .” But there ’ s no evidence that eating chocolate releases the hormone the way a simple act like hands touching or eyes meeting can release it .
Correct Answer : True The same brain areas light up in people who are madly in love and those who use cocaine or opioids . Lovers also show the classic symptoms of addiction . As a romance builds , a lover craves more and more of the “ drug ” -- the other person . A breakup can cause withdrawal symptoms like poor sleep and depression . And scorned lovers can relapse : Hearing a favorite song can trigger the craving all over again .
Correct Answer : Help people bond At orgasm , the hormones vasopressin in men and oxytocin in women rise . These “ cuddle hormones ” can flood you with loving feelings for your partner . Scientists believe these chemicals help cement emotional bonds between lovers . The chemicals of romance may wane at the same time , so ecstasy gets replaced with devotion .
Correct Answer : True Women with a trim waist and womanly hips may get more manly attention than other women , at least if you ’ re a line drawing !
Men shown drawings of women preferred those with a waistto-hip ratio of 70 % -- 25 1 / 2 inches by 36 inches , for example . And hundreds of art works from different cultures -- some dating back 32,000 years -- show this is not new . It may be a sign that a woman is a good mate .
Should you worry about your own shape ? Probably not . These studies only showed a front view , so who knows how a curvaceous behind might change the laws of attraction ?
Correct Answer : Body type In a study , men and women listened to recordings of people counting to 10 , and then ranked their attractiveness . Voices rated most attractive came from men with broad shoulders and narrow hips . For women , the most fetching voices came from those with narrow waists and broad hips .
Correct Answer : True In two small studies , Swedish researchers asked people to sniff chemicals made from male and female hormones . The male hormone testosterone turned on a sexual part of the brain in gay men and straight women -- but notin straight men . Brain responses were more complicated when people sniffed a female hormone . But more lesbians and straight men said they liked the scent of the female hormone , than did straight women .
Correct Answer : True Why do people with well-balanced facial features get more dates ? It ’ s a sign of greater ability to fight off disease . And research shows that to the symmetrical go the sexual spoils . Men with even features have sex earlier and with more partners , including after marriage . And women have more orgasms with them than with lopsided men .
