Do you know why women love men with self-deprecating humor?

Women love men with self-deprecating humor

Miss Finder –The Journo, tries to find answers for your general knowledge and awareness on: Do you know why women love men with self-deprecating humor?

Hey guys, you would simply love this, because I’m going to give you yet another clue to win your woman’s heart. Well, being a woman myself, I always like honest men with good sense of humor. And, I’m not alone – confirms the latest study! So, what's the most effective way of winning a woman's heart? Well, it is by running yourself down! Yes, you read it right – women, in general, just love men with self-deprecating humor!

I’m sure you guys would find it hard to digest, but guys, this is now a proven fact. Researchers have carried out the two-year study which revealed that taking the mickey out of one's self, works better than just clever jokes which might be seen as boastful and put women off.

Lead researcher Gil Greengross said, “Many studies show that a sense of humor is sexually attractive, especially to women. But we've found that self-deprecating humor is the most attractive of all. It is a risky form of humor because it can draw attention to one's real faults thereby diminishing the self-deprecator's status in the eyes of others. But based on the idea that verbal humor evolved to function as a fitness indicator, self-deprecating humor can be an especially reliable indicator, not only of general intelligence and verbal creativity, but also moral virtues such as humility.”

In fact, in the study into the role of humor in seduction, the researchers have found that the type of humor used by Hugh Grant in the film Notting Hill, in which he attempts to charm Julia Roberts with the poor contents of his fridge - works the best.

But beware guys, before taking the plunge because the London researchers have also warned that the technique should not be attempted by those who are already unpopular as it could make “low-status individuals” appear “more pathetic” than they did before.

The study is to be published in the upcoming edition of the Journal of Evolutionary Psychology.

So, it’s not the smartest of the men with the most intelligent sense of humor that attract this present age women, instead, men with self-deprecating humor, make their way into their hearts. Are you listening, guys?

Do you know why delayed fatherhood can cause miscarriage?

Delayed fatherhood causes miscarriage

Prof. Know Why answers for your general knowledge and awareness on: Do you know why delayed fatherhood can cause miscarriage?

Couples who want to start a family, better plan it early in your life because the more you delay, the stronger becomes the risk of a miscarriage, say the scientists. And this applies to both men and women. Contrary to the older belief that men remain fertile even at old age, this new research points out that delayed fatherhood can also cause miscarriage like late motherhood.

Delayed fatherhood for men is a cause of concern for a healthy pregnancy and the baby as well, doctors warn, after a recent research found that male fertility begins to decline when they reach their mid-30s. Doctors said men who wait until their 40s before starting a family face a greater chance of their partner having a miscarriage, because of the poorer quality of their sperm.

The researchers studied the records of more than 12,000 couples treated for infertility at the fertility clinic, Eylau Centre for Assisted Reproduction in Paris between January 2002 and December 2006; and separated out the influence of male and female ages on the couples' chances of having a baby. They found that women whose partners were 35 or older had more miscarriages than those who were with younger men, regardless of their own age. The men's ages also affected pregnancy rates, which were lower in the over-40s.

The study looked at pregnancies and miscarriages recorded for couples having IUI treatment at the clinic. It found the risk of miscarriage was on average 16.7% when men were aged 30-34. That rate rose to 19.5% when men were 35-39 and 33% in men aged 40 or over.

The findings are a concern, researchers say, because of the trend for men to delay fatherhood. Stéphanie Belloc, lead author of the study, said that until now, gynecologists only focused on maternal age, and the message was to get pregnant before the age of 35 or 38 because afterwards it would be difficult. But now the gynecologists must also focus on paternal age and give this information to the couple.

Yves Ménézo, an embryologist at the Eylau Centre for Assisted Reproduction, said older men become less fertile because genetic defects build up in their sperm. In younger men, the damage is minor and can be repaired inside the fertilized egg. But in older men the amount of DNA damage can overwhelm the body's natural repair mechanisms. "We think there's a critical threshold of DNA damage and above that, the damage can no longer be repaired. When that happens, genetic mistakes get through to the embryo and you get an increase in miscarriages," Ménézo said.

Jacques de Mouzon, a co-author at the French National Institute for Medical Research, said: "People say men are fertile into old age, 90 even. That may be true sometimes, but the product is different and there are more semen abnormalities as age advances. There is a decrease [in male fertility] and an increase in the spontaneous abortion rate after the age of 40 and especially after 45. It is necessary for men to try to have children before the ages of 40 to 45."

Previous research has pointed to a slight increase in birth defects in babies born to older men. A 2005 study of 70,000 couples by epidemiologist Jorn Olsen at the University of California, Los Angeles, found a fourfold rise in Down's syndrome among babies born to men aged 50 and older. They were also more likely to have limb deformities.

Dr Allan Pacey, a fertility expert at Sheffield University and secretary of the British Fertility Society, said: "There is growing evidence from a number of studies to show that men are not totally immune from reproductive ageing. "Previous studies of couples trying to conceive naturally or undergoing IVF have shown that men over the age of about 40 are less fertile than younger men. Moreover, if they do achieve a pregnancy their partners are more likely to miscarry. This study reinforces the message that men aren't excused from reproductive ageing."

Normally, men don't typically worry about reproductive ageing, but perhaps they should if the study is to be believed, as now, delayed fatherhood is also being linked to miscarriages, and birth deformities.

Do you know why women are more attracted to men with stubble?

Miss Finder –The Journo, tries to find answers for your general knowledge and awareness on: Do you know why women are more attracted to men with stubble?

All young men, do you know what it takes to get into a woman’s heart? Well, stubble is the way to win a woman’s heart, so says a study. Researchers found that women are more attracted to men with stubble than those with clean-shaven faces or full beards.

The findings of the experiment, carried out on British women aged 18 to 44, could explain the appeal of actors such as George Clooney and Brad Pitt who cultivate their unshaven look.

Women who participated in the research rated men with stubble as tough, mature, aggressive, dominant and masculine — and as the best romantic partners, either for a fling or a long-term relationship.

To justify this preference of women, the experts in human evolution have given a weird explanation, that facial hair may be a signal of aggression because it boosts the apparent size of the lower jaw, emphasizing the teeth as weapons. An unusual and funny reasoning, if you ask me — isn’t it?

Well, psychologists at Northumbria University, who actually carried out the new study, explain differently. They believe that stubbly men may offer women the best worlds — not too strongly masculine, but mature and with the potential to grow a full beard.

The researchers carried out the study using computer technology to alter pictures of 15 men’s faces so that they displayed different degrees of hairiness. Five levels were used — clean-shaven, light stubble, heavy stubble, light beard and full beard.

The pictures were shown to 76 women who were asked to rate them for masculinity, aggression, dominance, attractiveness, age, and social maturity.

Pictures of men with full beards were judged to be the most masculine, aggressive and socially mature. But they were rated the least attractive and the worst choice for a short-term relationship.

Men with light beards were considered the most dominant. Those with light stubble were rated the most attractive and as the ideal romantic partner for the short or long term. Clean-shaven men finished bottom for masculinity, dominance, aggression, and social maturity.

Well, gone are the days, when women used to like her man to be elegant with clean-shaven look. The 21st century women are more attracted to the rough macho look instead, that signifies more masculinity in men with stubble. And if you ask me, I simply find stubbly men, hot — yes, that’s the word! So get ready guys — now you know the way to a woman’s heart!

Do you know why masturbation reduces the risk of cancer?

Prof. Know Why answers for your general knowledge and awareness:

People have always linked masturbation with adult topics of discussions as because the first thought that comes with the word masturbation, is sex and lust. The society is normally hesitant and feels awkward to discuss on the subject of masturbation, openly and freely. Well, that is fine! But do the elders know the benefit of masturbation? I bet, not! A recent research-study has discovered an amazing fact about masturbation that may change the outlook of the society on the whole.

Researchers have found out that men who masturbate regularly are at a reduced risk of developing prostate cancer.

Yes, you read it right! In the study, Australian researchers concluded that frequent masturbation may help men cut their risk of contracting prostate cancer. It is believed that carcinogens may build up in the prostate if men do not ejaculate regularly, reported BBC News.

The researchers surveyed more than 1,000 men who had developed prostate cancer, and 1,250 men who had not. They found that men who had ejaculated the most between the ages of 20 and 50 were the least likely to get cancer. Men who ejaculated more than five times each week were a third less likely to develop prostate cancer.

Sexual intercourse may not have the same effect because of the higher risk of contracting a sexually transmitted disease, which could in turn raise the risk of cancer. "Had we been able to remove ejaculations associated with sexual intercourse, there should have been an even stronger protective effect of ejaculations", Graham Giles of the Cancer Council Victoria, who led the researchers, said in the article.

The prostate produces a fluid that is incorporated into ejaculation, which activates sperm and prevents them from sticking together. Studies on animals have shown that carcinogens like 3-methylchloranthrene can be harbored in the prostate. Frequent ejaculation encourages the cancer-inducing fluids to flush out.

So, do I still need to say, “Carry on men” or you have already got the message?

Do you know why men are dumb dates?

Miss Finder –The Journo, tries to find answers:

Men usually think they are the smarter sex. But when it comes to flirting they often prove out to be real dumb or boring dates, should I say? Just don’t overreact, all you men! A recent study claims that you just can’t read signals coming from the fairer sex. So, men those who consider flirting to be your traditional domain, think again!

To put it straight - men just don’t understand the attitude and advances of women. The flutter of eyelashes, the smile across the dance floor and the giggle after a lame joke - every woman knows the time-honored ways to get a man. But, men stand dumb to these subtle seduction techniques of the opposite sex, when dating. So, short of pouncing on the object of her lust, a woman’s non-verbal signals of sexual interest often prove sadly lost in the young male brain.

According to the study by the researchers at Indiana University, rather than going through life thinking “she wants me”, men often find themselves trying to navigate a foreign world of social signals without a phrasebook.

Kathy Lette, a best-selling author, says that the research is further evidence of women’s superiority. “Women are fluent in body language; men just have the gift of the ‘grab’. It is really confusing for women. The average bloke either doesn’t realize that we fancy them until we are giving birth to their children in the labor ward; or he presumes all women fancy him all the time. God was playing some kind of prank when he developed two sexes.” - Are you men listening?

Many men out there might get miffed, but the fact is that the male species fall flat on its face when it comes to gauging the female psyche in the initial dating period. “Men find it difficult to tell the difference between women who are being friendly and women who are interested in something more,” claims Coreen Farris, the lead researcher of the university’s Department of Psychological and Brain Sciences.

Well, doing my own survey, interviewing a few men in my reach, I found out that there are some men out there who admit that they tend to go haywire while reading signals from the fairer sex and just go off-track while trying to read the expressions or body language of their womenfolk.

To conclude on the topic from my findings, I would say, men usually tend to err in their judgment of feminine ways because they probably believe in clichés. Their minds are not properly attuned to understand the delicate signals given by modern women. And, they normally stick to their preconceived notions about women and read what they want to.

But the few witty and intelligent of the male species may find some solace in Coreen Ferris, who believes “these are average differences. Some men are very skilled in reading clues.”

So, the time hasn’t yet arrived for women to ditch the lipstick at once because not all flirting gets lost in translation after all!

Do you know why women are attracted to men with darker skin?

Prof. Know Why answers for your general knowledge and awareness:

Have you ever wondered why women are attracted to men with darker skin, while men prefer fair-complexioned females? Well, the attraction is driven by preferences based on moral assumptions, says a study.

Researchers from the University of Toronto, who conducted the study, said that women are predominantly attracted to men with darker skin because of latent thoughts about sex, mystery and danger. The findings suggested that, women would be naturally drawn to George Clooney over fellow actor and fairer-skinned, Daniel Craig.

On the other hand, men prefer fair-complexioned women. In fact, more men would instinctively prefer Keira Knightley than her Spanish counterpart Penelope Cruz. Researchers observed that lighter-skinned women in all races are seen as the ideal because of a subconscious association with innocence, purity, modesty, virginity, vulnerability and goodness.

The study was conducted on the basis of 2,000 advertising photographs of men and women, as models were considered the most attractive people of their races and genders.

“What the research shows is that our aesthetic preferences operate to reflect moral preferences. Within our cultures, we have a set of ideals about how women should look and behave. Lightness and darkness have particular meanings attached to them and we subconsciously relate those moral preferences to women and men” - said the study’s lead author Dr Shyon Baumann, a sociologist at the Toronto University.

According to the researchers, many judgments about beauty are made at a conscious level - such as about leg length, height, weight and the shape of the nose as well as the mouth. But, other physical attractiveness ideals, including complexion, are made at the subconscious level.

Do you know why men should chuck smoking and drinking for offspring?

Prof. Know Why answers for your general knowledge and awareness:

We all learned people know that too much of smoking or drinking is injurious to our health as science has long been clear that smoking or heavy alcohol consumption causes cancer. But, a new study has found that babies could inherit genetic damage from a father who puffs or drinks heavily.

A team of international researchers has found that smoking or drinking alcohol can cause chemical changes in the semen in men and the alterations could be potentially inherited by their offspring and their future generations.

The researchers came to the conclusion after they analyzed the effects of smoking and heavy drinking — both toxic in nature — on a group of mice. They gave pregnant female mice daily injections of pesticide vinclozolin during the period when the sex of embryos is determined. Male offspring had abnormalities, including prostate and sperm development problems, and genetic changes that the researchers found were passed on through four generations when the males were mated with healthy females.

The researchers have also identified specific genes involved in the production of sperm that were permanently altered by the exposure to the pesticide. "In addition to the spermatogenic and prostate abnormalities, trans-generational effects on numerous disease states were observed including tumour development and kidney disease”, said Matthew Anway of the University of Idaho.

Anway said the doses used, far exceeded the levels that humans could expect to be exposed to, but the study was designed to demonstrate how toxins lead to inheritable abnormalities.

"Studies have shown significant associations between male toxic exposures and increased rates of infertility, miscarriage, stillbirth and childhood health problems to open our eyes and look at the evidence" and "when you harm the male reproductive system you can see multi-generational harm transmitted through the male gamete (sperm). This research has human implications as it suggests an avenue of harm and a model of trans-generational effects”, said co-researcher Dr Cynthia Daniels of the Rutgers University.

Before it becomes too late, one thought-provoking question to the men of these bad habits, who are yet father a child - you might justify the privilege of living your own life on your preferred terms, but do you sincerely have the right to snatch away a desired healthy life from your offspring?

Do you know why people are straight or gay?

Prof. Know Why answers:

There has always been a debate about the reasons of a person’s sexual orientation - Is sexual orientation something people are born with or a matter of choice? Well, in the latest study that is bound to re-ignite the debate, it is weighed more on the side of genetics.

So, why are people straight or gay? Researchers at McMaster University and Sunnybrook Health Sciences Centre in Toronto have found new evidence that shows that your genes are what make you straight or gay. Led by neuroscientist Sandra Witelson, the study scanned the brains of healthy, right-handed homosexual and heterosexual men using magnetic resonance imaging (MRI).

A decade back, Witelson had demonstrated that there are more left-handers in the homosexual population. Handedness is a sign of how the brain is organized to represent different aspects of intelligence. Language, for example, is usually on the left and music on the right. In other researches, Witelson had also found that left-handers have a larger posterior corpus callosum (the band of nerve fibres connecting the two hemispheres of the brain) than right-handers.

This raised the hypothesis for the current study - whether the anatomy of the brain of the sub-group of right-handed homosexual men is similar to that of left-handers. The researchers found that the posterior part of the corpus callosum is larger in homosexual than heterosexual men. As the size of the corpus callosum is largely inherited, it suggested a genetic factor in sexual orientation.

“Our results do not mean that heredity is destiny, but they do indicate that environment is not the only player in the field,” said Witelson. The finding may be one additional piece of information for individuals trying to determine their sexual orientation as “sometimes people aren't sure of their sexual orientation”, added Witelson.
