Why women have colder hands but men have BIGGER noses!
Ever wounder why women love holding hands on chilly walks well the real reason according to,A Cambridge university study revealed last week that because women's hands tend to suffer cold more than men`s,its all down to muscle tissue of which men generally have more than women and which is largely responsible for generating body heat that keeps us warm.
this was discovered from the test in which scientist made hardy volunteers plunge their hands into ice cold water for three minutes and then monitored how quickly their hands warmed up
The men ,with greater muscle mass ,warmed up quicker than women whose hands have more fatty tissue,fatty tissue is less effective thermal insulator insulator because salt inside the fat makes it a good electrical conductor,
Stephanie Payne,a biological anthropologist who led the research ,should be applauded as in recent years scientist who dared to point out differences between men and women have been roundly criticized For while all aspects of modern life — from the bedroom to the boardroom — are increasingly geared to ensure equality for all, Mother Nature keeps some distinctly tricks up her sleeve when it comes to basic physiology.Believe it or not, science even reveals that some of the old battle-of-the-sexes cliches are entirely true — yes, men really are worse at listening during conversations
Even if a woman and a man are physically the same size, the man’s nose is on average 10 per cent bigger.Why? It appears that men’s bodies need more oxygen, so they grow bigger hooters in order to suck it all in. A study in 2013 by Nathan Holton, a professor of orthodontics at the University of Iowa, explains why.Holton followed 20 men and 18 women from the age of three until their mid-20s to monitor the way in which their skulls grew. He found that boys’ skulls went through a growth spurt during puberty that put them a nose ahead.This is the stage of life when boys begin to grow more lean muscle mass, while girls grow more body fat mass.Lean muscle requires more energy — in the form of oxygen — for building and maintenance than body fat, explaining the need for boys to suddenly need more air.
Men are also far more likely to have a form of colour blindness, It’s not only ducks and dragonflies that have very different colourings according to their sex.Human skins have different sexual ‘plumage’ too, according to researchers at Brown University in Rhode Island, U.S.They analyzed more than 300 faces to find a subtle yet fundamental gender difference in human faces: men are tinged red while women are tinged green
Humans are the only species where the sexes have differently shaped spines. This biological curiosity has long puzzled scientists. It also puts millions of women at risk of the bone-thinning disease osteoporosis.Now biologists say that women’s bodies have evolved this way because only a thinner spine enables them to carry a pregnancy while at the same time walking upright.
Women’s noses may be smaller, but their brains can read much more from the air they do breathe in. According to Brazilian researchers, women have more than 40 per cent more cells in the olfactory bulb. In 2014, a team from the Federal University of Rio de Janeiro studied the brains of deceased adults and found that while men had some 9.2 million cells in their olfactory bulbs, the women had around 16.2 million. According to science, women evolved this trait to choose mates for reproductive purposes — by detecting subtle changes in men’s testosterone levels that indicate how fit, strong and healthy they are.
what an interesting article! the author well done! thanks for the post! now I will be

Nice article. Please include your sources.
At what month of pregnancy can gender of a fetus be determined and in what trimester do RBC`s start forming in am embryo ie what trimester
Not sure, I think around the 2nd trimester.
1st trimester rbcs produced by liver first the yolk sac i think id better just ask questions
oh then for the identification of sex its 4 of 5 month of pregnancy
i really enjoyed this article. thanks
i thought of taking pictures of plants on the farm like cassava,beans groundnut ,you things that Europeans never see.do you think it would be appreciated
