10 interesting facts about gender psychology

1. Men change their minds two to three times more often than women. Most women take longer to make a decision than men do, but once they make a decision they are more likely to stick to it.

2. Based on the total number of people tested since IQ tests were devised, women have a slightly higher average IQ than men

3. Women are better than men at remembering faces, especially of females.

4. Men are more likely to help than women!

5. Women are more pessimistic when predicting their work results.

6. Most women tend to believe that they are only good at certain tasks, but not capable of being good at everything.

7. Women are more fearful and anxious than men.

8. Women are twice more talkative than men! It has been estimated that on average, men speak 12,500 words and women speak about 25,500 words in a day.

9. Men, on average, think about sex every 7 seconds.

10. The female brain is much more adept at reading subtle facial and verbal emotional expressions.  Some woman say that only when men see actual tears they realize that something is wrong. This is why women have to cry four times more than men do, to signal distress.

Radiation from Wireless Internet Connections Might Damage Sperm Cells

A computer with a wireless Internet connection hurts sperm, but not because the machine can heat up your lap, a new study suggests.

The findings showed that sperm cells collected in lab dishes and placed beneath a laptop with a wireless Internet connection for four hours had less motility and more DNA damage than sperm placed in another room, away from electronic devices but kept at the same temperature.

"It is well-known that increased temperature may decrease sperm quality, and the use of portable computers on the lap increases scrotal temperature," the researchers wrote in their study. 

But the findings suggested it wasn't the temperature beneath the laptop that was affecting sperm; instead, the radiation from the laptop was slowing the swimmers, according to the study.  

Laptops emit radiation

The researchers in Argentina and Virginia used semen samples from 29 healthy men, whose average age was 34. The laptop was set to download and upload information over the course of the experiment, so the wireless connection was actively being used. The temperature under the laptop was held constant at 25 degrees Celsius by an air-conditioning system.  

Wireless Internet connections use radio-frequency electromagnetic waves. When the researchers measured the radiation coming from a laptop wirelessly connected to the Internet, they found it was at least three times higher than an unconnected laptop, and seven to 15 times higher than radiation in a general setting, according to the study, though the levels varied over the course of the experiment, depending on the flow of information coming to or from the computer.

There was no difference between the sperm samples held under the laptop and those kept away from it in terms of the percentage of sperm that were dead at the end of the experiment, according to the study.

Still, sperm motility and having undamaged DNA are important for fertilizing an egg.

"We speculate that keeping a laptop connected wirelessly to the Internet on the lap near the testes may result in decreased male fertility," the researchers wrote in their conclusion.

Why sperm cells are vulnerable

Sperm cells are different from other cells in the body — their DNA is highly condensed into a small area, the researchers noted. This could make them more vulnerable to the effects of such radiation.

It's plausible that the magnetic and electromagnetic fields produced by the radio waves damage molecules in sperm called phospholipids, which are a needed to keep membranes within a sperm cell intact, the study researchers wrote.

It is not known whether all laptop computers might have the same effects as those seen in this study, nor is it known what other factors might heighten or lessen the damage, the researchers wrote in their conclusion.

"However, we cannot discard the possibility that damage to sperm is caused by the low radiation produced by the computer without Internet connection," they wrote, and this possibility should be studied further.

The study was published online Nov. 23 in the journal Fertility and Sterility.

Eating Chicken May Lead to a Smaller Organ for men!

According to the best available science, three quarters of women find the size of a man’s penis to be either “somewhat important” or “very important.”

What does this have to do with chicken?:Phthalates.

 Phthalates are chemical compounds used in a wide range of consumer products, including pesticides, paints and PVC plastic. However, the contribution of dietary intake to phthalate exposure was not well defined until a landmark study was published last year in the journal of the U.S. National Institute of Environmental Health Sciences. 

Pthalates had been known to affect the genital development of lab rats, but recent human studies have also shown adverse effects on sexual health and development.

The most important findings to date have come from the Study for Future Families, a multicenter study of prenatal clinics in California, Minnesota, and Missouri.

Researchers measured the levels of phthalates flowing through the bodies of pregnant women, and then later measured the size and characteristics of their infant sons’ genitalia between the ages of two months and three years.

Women who had the most phthalate exposure had up to ten times the odds of giving birth to sons with one or both testicles incompletely descended, their scrotum categorized as small and/or “not distinct from surrounding tissue” and a significantly smaller penile volume, a measure of penis size taking into account both length and girth.

 In other words, the more phthalates pregnant women are exposed to, the “increased likelihood of testicular mal-descent, a small and indistinct scrotum and smaller penis size.”

The team of researchers conclude: “These changes in male infants, associated with prenatal exposure to some of the same phthalate metabolites that cause similar alterations in male rodents, suggest that commonly used phthalates may undervirilize humans as well.”

So what foods should pregnant women stay away from in order to avoid the “phthalate-related syndrome of incomplete virilization” in their sons?

In a study published last year, the level of phthalate in the urine of thousands of Americans were measured, along with their diets to find out which food was most significantly associated with phthalate body burden.

They looked at dairy, eggs, fish, fruit, poultry, potatoes, tomatoes, vegetables in general and red meat. The most significant correlation in poultry consumption.

The data suggested that, “an increase of one ounce of poultry per day is associated with an increase in [phthalate] DHEP levels of approximately 5.7 percent.” A single chicken breast can weigh 8 ounces(0.227kgs).

Perhaps the phthalates were leaching into the meat from the plastic packaging. Probably not, the researchers concluded, “the finding that egg consumption is significantly associated with levels of MHEP [phthalates] too, suggests that chickens themselves may be contaminated with phthalates and that food is not being contaminated just through packaging and processing.”

So to protect their son’s normal development, pregnant women may be wise to avoid poultry

12. The human heart creates enough pressure while pumping to squirt blood 9metres(30feet)!

13. The brain operates on the same amount of power as 10-watt light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark. Your brain generates as much energy as a small light bulb even when you’re sleeping.

14. The brain is much more active at night than during the day.

15. The brain itself cannot feel pain. While the brain might be the pain center when you cut your finger or burn yourself, the brain itself does not have pain receptors and cannot feel pain.

16. The fastest growing nail is on the middle finger. And the nail on the middle finger of your dominant hand will grow the fastest of all. Why is not entirely known, but nail growth is related to the length of the finger, with the longest fingers growing nails the fastest and shortest the slowest.

17. The lifespan of a human hair is 3 to 7 years on average.

18. Human hair is virtually indestructible. Aside from it’s flammability, human hair decays at such a slow rate that it is practically non-disintegrative. Hair cannot be destroyed by cold, change of climate, water, or other natural forces and it is resistant to many kinds of acids and corrosive chemicals.

19. The acid in your stomach is strong enough to dissolve razorblades. Hydrochloric acid, the type found in your stomach, is not only good at dissolving the pizza you had for dinner but can also eat through many types of metal.

20. The surface area of a human lung is equal to a tennis court.

21. Sneezes regularly exceed 100 mph.

22. Approximately 75% of human waste is made of water.

23. The average person expels flatulence 14 times each day. Even if you’d like to think you’re too dignified to pass gas, the reality is that almost everyone will at least a few times a day.

24. Earwax production is necessary for good ear health. While many people find earwax to be disgusting, it’s actually a very important part of your ear’s defense system. It protects the delicate inner ear from bacteria, fungus, dirt and even insects. It also cleans and lubricates the ear canal.

25. Babies are always born with blue eyes.  The melanin in a newborn’s eyes often needs time after birth to be fully deposited or to be darkened by exposure to ultraviolet light, later revealing the baby’s true eye color.

26. Every human spent about half an hour as a single cell.

27. After eating too much, your hearing is less sharp.

28. Women are born better smellers than men and remain better smellers over life.

29. Your nose can remember 50,000 different scents.

30. Nails and hair do not continue to grow after we die. They do appear longer when we die, however, as the skin dehydrates and pulls back from the nail beds and scalp.

31. By the age of 60, most people will have lost about half their taste buds. Perhaps you shouldn’t trust your grandma’s cooking as much as you do.

32. Your eyes are always the same size from birth but your nose and ears never stop growing.

33. By 60 years of age, 60-percent of men and 40-percent of women will snore.

34. Monday is the day of the week when the risk of heart attack is greatest.  A ten year study in Scotland found that 20% more people die of heart attacks on Mondays than any other day of the week. Researchers theorize that it’s a combination of too much fun over the weekend with the stress of going back to work that causes the increase.

35. Provided there is water, the average human could survive a month to two months without food depending on their body fat and other factors.

36. Over 90% of diseases are caused or complicated by stress.

37. A human head remains conscious for about 15 to 20 seconds after it is been decapitated. While it might be gross to think about, the blood in the head may be enough to keep someone alive and conscious for a few seconds after the head has been separated from the body, though reports as to the accuracy of this are widely varying.

38. Babies are born with 300 bones, but by adulthood the number is reduced to 206.

39. We are about 1 cm taller in the morning than in the evening.

40. It takes twice as long to lose new muscle if you stop working out than it did to gain it. Lazy people out there shouldn’t use this as motivation to not work out, however. It’s relatively easy to build new muscle tissue and get your muscles in shape, so if anything, this fact should be motivation to get off the couch and get moving.

41. Tears and mucus contain an enzyme (lysozyme) that breaks down the cell wall of many bacteria.

42. It is not possible to tickle yourself. Even the most ticklish among us do not have the ability to tickle ourselves.

44. Humans are the only animals to produce emotional tears.

45. Women burn fat more slowly than men, by a rate of about 50 calories a day. Most men have a much easier time burning fat than women. Women, because of their reproductive role, generally require a higher basic body fat proportion than men, and as a result their bodies don’t get rid of excess fat at the same rate as men.

47. Koalas and primates are the only animals with unique fingerprints. Humans, apes and koalas are unique in the animal kingdom due to the tiny prints on the fingers of their hands
