Is This Something Men Should Be Paying Attention To?

It’s generally accepted that a decent man should pay attention to his health, fitness, moods and demeanor, and do everything possible to be the so-called “ideal man”. But there’s one little detail that many men do not pay attention to, and which there’s some debate about whether it’s necessary. I’m talking about shaving below-the-belt, or “manscaping”. So should men manscape?

If you’re of the opinion that men should manscape, the next question is how to do it. A normal razor is hardly appealing when it comes to shaving such sensitive areas, and an ordinary electric razor is also not perfect. Special care obviously has to be taken. That’s why the MANSCAPED brand was born. Manscaped, featured on Shark Tank, is a product designed specifically for shaving below the belt.

Manscaped’s products are not cheap, being around $90 for their main product. Whether that’s worth it is not clear, as although many reviews are positive, there are those who say it’s overpriced.

If you’re contemplating buying Manscaped, I recommend reading this review and summary of Manscaped here. The author there gives a good rundown of the company and his own experience trying the razor, and also lists a couple of reviews from other people.

INUIT PARKA IS THE BEST COAT EVER INVENTED

The technology of the Inuit parka with its multiple layers and the edge of the hood’s hair make them the best coat invented by humans

When it comes to keeping warm in winter, few people know more than the Inuit the Arctic circle. The traditional parka is an engineering prodigy, and the most efficient coat designed by humans in its history.

In its traditional version this coat consists of two layers of caribou skin. The inner layer has the hair in, in contact with the skin, and the outer layer has the hair out. This superposition of layers of skin and hair creates an insulating air chamber around the body very effective.

Much more interesting is the function that the hair has around the edge of the hood, characteristic of the parka. A 2004 study put one of these hoods in a wind tunnel to see what its effect was. The hair on the hood changes the air flow in the face, preventing excessive heat loss. This seems to work only with natural skin, which has hairs of different lengths, and not with the synthetic skin in which they are uniform.

Similar parkas or coats could also have been what saved our species during the last glaciation, according to the theory of researcher Mark Collard. At the same time, a possible explanation for the disappearance of Neanderthals, who were physically better prepared for the cold, is that they did not have adequate clothing to protect themselves, which limited their hunting ground.

Modern parka somewhat mimics the traditional design: a hollow fiber filling, a waterproof and windproof, but breathable, intermediate layer and finally a stronger outer layer. A design that is thousands of years old.

Science Answers: What Is Pansexuality?

First off, what is pansexuality? It is a concept that goes back as far as the time of Freud, and there have been a number of studies on it. It may be loosely defined as someone who is sexually attracted to a person regardless of the sex of that person, as defined by sociologist Emily Lenning. Now, a new study published in the Journal of Sex Research is claiming that among non-heterosexual pansexual people, there are a staggering 5 times as many women than men. It is also more likely for people who identify as some gender other than male or female to consider themselves pansexual, and more likely for younger people to consider themselves pansexual.

While these studies are making some headway into how many pansexual people there are and how they view things, there is still a lot of work to be done, and the numbers are still somewhat unclear. “Pansexual” is rarely offered as an option in research studies, and therefore the exact percentage of the population that would consider themselves pansexual is still unclear.

You may be wondering, based on the above definition, what is the difference between pansexual and bisexual? Another study also published in the Journal of Sex Research has explored these differences and concludes that those who consider themselves pansexual are longer, more likely to be of a diverse gender (eg. transgender or non-binary) and tend to be more politically liberal.

Can Children Be Turned Into Aquaman? Possibly

Is it possible to see underwater with clarity, just with our bare eyes? Anna Gislen, from Lund University in Sweden, says that it may be possible. To test her hypothesis, she set up an experiment where she analyzed how good the vision of Moken children is, who have lived on the islands of Southeast Asia for hundreds of years. From a very young age, these children learn to swim and dive. In Gilsen’s study, published in Vision Research, she had Moken children dive underwater and look towards a panel that would show vertical or horizontal lines – they would then have to report which direction the lines were going once they surfaced. Each time they dived the lines became thinner, making the task more and more difficult.

The results of the study were that Moken children could see twice as well as Europeans who performed the same experiment.

According to Gislen, to have had results like this, Moken children must have some kind of fundamental adaption that changed how their eyes worked. She wanted to know whether one could learn this ability and get better with practice. Thus, in a follow up experiment over a full month, she had the European children – who initially has underwater vision far worse than the Moken children – train over 11 sessions, after which they reached the same quality of vision as the Moken children.

More studies may need to be done in this area, but these early results are very encouraging: it would appear that one can vastly improve their underwater vision, just by practicing.

Climate Change May Have A Huge Affect On Poverty

A new preliminary report by the United Nations Human Rights Council has suggested that climate change may result in hundreds of millions of people being pushed back into poverty, thus potentially cancelling the past fifty years of progress in worth health and poverty reduction. Climate change, according to the report, can easily result in food shortages, forced migration, diseases and more.

The authors of the report make the claim that 120 million people will be pushed into poverty by 2030 as a result of climate change. It gives some rather shocking statistics, including that since 2000 poor people were 7 times as likely to die of natural disasters than rich people, and that while 3.5 billion people are responsible for 10% of greenhouse gas emissions, the wealthiest 10% of people in the world is responsible for half of the emissions.

“In a perverse way,” the report points out, “the richest, who have greater capacity to adapt and are responsible for the vast majority of greenhouse gas emissions, will be the best placed to deal with climate change, while the poorest, who have contributed less to emissions and have less reaction capacity, will be the most affected. A simple fact: a person in the top 1% of the richest on the planet generates 175 times more CO2 than one who is among the 10% poorest.”

The report concludes as follows: “The human rights community, with some notable exceptions, has been as accommodating as most governments in the face of the challenge to humanity represented by the climate change. The steps taken by most United Nations human rights bodies have obviously been inadequate given the urgency and magnitude of the threat. This report has identified a series of steps that must be taken to begin rectifying this fact that human rights cannot survive the coming turmoil. It has also sought to highlight the fact that the most affected will be those living in poverty. Climate change is, among other things, an excessive assault on the poor.”

With all the news recently on climate change being about how our environment will suffer and how the lives of people in first world countries may change, we see this report as very important, as few people have deeply considered the effect climate change will have on the poorest and most vulnerable.

What Determines If A Lost Wallet Is Returned? Science Has The Answer

If you find a lost wallet, would you return it? A new study has analyzed this question and come to some very surprising results. According to this study, published in Science, the more money there is in a wallet, the more likely it is to be returned. That goes completely against what I had personally imagined (that the more money there is in a lost wallet, surely the less likely it would be to be returned).

This study was led by Michel Marechal and was carried out across 355 cities in 40 countries, and involved 17,000 lost wallets that they would leave in places like hotel receptions, museums or post offices. Each wallet had a different amount of money in it, along with a business card, shopping list and a key.

According to the researchers, there were 4 factors that influenced whether a lost wallet was returned: the monetary incentive to keep the money, the effort involved in getting in touch with the owner, altruistic considerations and the so-called “psychological cost of being dishonest” (where keeping an item someone else lost is usually seen as robbery, and someone taking a lost wallet has to live with that).

Beyond the interesting finding that the more money a wallet had in it, the more likely it was to be returned, researchers found that there was a huge variation in different countries. Switzerland, Norway, Holland, Denmark and Sweden were the most honest countries, as the vast majority of wallets were returned (between 70 and 85%). However, countries such as China and Kenya has far worse, with only around 20% of lost wallets being returned.

New Research Reveals Why Parents Are So Hard On Themselves

Parents are accustomed to listening to suggestions on how to be better parents. But how do parents tend to respond to all kinds of criticism from different people, and is it actually helpful? A new survey conducted by the CS Mott Children’s Hospital may have the answer. According to the study, many parents respond well to criticism, but other parents do not – and that can have very negative consequences. “While some parents say criticism encourages them to seek more information about good practices, too much contempt can make parents feel demoralized about their fatherly role,” explains Mott’s survey co-director, Sarah Clark. “Parents who love and commit can have a positive impact on the development and well-being of their children, but different family members should be willing to recognize that there are different parenting styles without necessarily being wrong or harmful,” she adds.

According to the researchers, the hardest type of criticism that parents face is how to discipline their children, and it is also very common for a husband and wife to argue about when their child should start to receive proper discipline. “Addressing misconduct is one of the biggest challenges of raising children, and parents are not always on the same page when it comes to expectations and consequences,” the researcher acknowledges.

Other than on how to discipline children, how are parents often criticized? One interesting point is that it is often the father, not the mother, who tends to be seen as the incompetent parent, according to the results of the survey. Often, a father playing with their child may be criticized for not properly protecting the child from injuries, for example. Clark comments on this as follows: “In some cases, this may be a reflection of historical gender roles, where mothers are considered born caregivers, while fathers bear the prejudice of having a limited parenting capacity and need supervision or correction.

Researchers Ask: Are Prisons The Best Way To Stop Violent Criminals?

A study conducted by the sociologist David Harding from the University of California at Berkeley has concluded that locking up criminals who committed assaults, robberies and similar crimes does little to prevent them for committing these crimes again once they get out of prison. The whole findings were published in the Nature Human Behavior publication, and question whether the strict standards we have against crime now (such as mandatory minimum sentences) are very effective.

“We are investing too much money in prisons and the benefit in terms of public safety is very low,” says Harding. Harding and his team analyzed how often it was that criminals would commit crimes again after being released from prising, analyzing more than 100,000 people in Michigan that were found guilty between 2003 and 2006, and continued to track their activity up until 2015. Their analysis mainly focused on cases where the judges had the option of sentencing defendants to prison or probation.

The results show that people who were on parole for 5 years after committing a crime, and those who went to prison for 5 years after committing a crime, were roughly equally likely to go out and commit crimes again as soon as they could. “The conclusion here is that incarceration does not make a dent in violent crime rates,” says Harding. “Our findings show that we could imprison fewer people convicted of violent crimes and invest savings in other ways to prevent violence in society.”

Clearly this is an area where further research is needed, as researchers have not made a firm conclusion on what “other ways to prevent violence in society” are most effective.

How Much You Earn May Be Written In Your DNA, Study Says

What do the richest people in the world have in common? A study from the University of Edinburgh has come to an interesting conclusion: these people may share the same genes of wealth. A team led by David Hill looked into the UK Biobank database, which contains over 500,000 genetic profiles of people living in the UK, to try to find commonalities between wealth and DNA. This is an unusual study, and to the best of our knowledge, the first that has been done of this kind.

The study involved taking 286,000 people in the UK Biobank and then dividing them automatically according to income level. For people with lower income, Hill found that there were less advantageous genetic variants, while in the wealthiest group he found several commonalities that could be attributed to a higher level of intelligence. The question is whether that is enough to determine that DNA and wealth are closely correlated.

One of the issues with this study, as mentioned by Julien Larregue, is that it is hard to exactly define the concept of intelligence and that there are many factors that go into someone’s income level. After all, the same person with the same DNA may easily earn differently if they were born in a different country or had a difficult upbringing.

The closest study we found to Hill’s study (where researchers linked income to some other trait) was this one led by Philipp Koellinger, where more than 800,000 people were analyzed to try to calculate someone’s income based on job type, age and sex. But as far as determining with definite certainty whether DNA will influence income, there is just the 1 study for now.

Stress Among Teachers Is Worse Than We Thought

A study published in the British Journal of Educational Studies has raised the issue of the quality of life that teachers experience. In the study, 1200 teachers were interviewed, and of those just over half reported that they wanted to leave the profession after 10 years. The main reasons given for this were the high workload and the desire for a better work-life balance. In regards to workload, many teachers found that they disliked being supervised and the bureaucracy of teaching.

While most respondents reported that they say teaching as a long term career (75%), not so many teachers reported that they were happy with their job or that they actually intended to stay doing it forever.

As far as the reasons the study found for why people wanted to become teachers, the main reasons were making a difference (about 2 in 3), working with young people (64%) and love for teaching (1 in 2). But once these people started teaching, the boredom and difficulty of the job often dampened their enthusiasm, according to the study.

While many teachers expected a high workload before starting the profession, many reported that it was even higher than they expected, and too much of the job was not focused on teaching, but rather marking exams, evaluation, preparing for reviews and so on – the least creative areas.

“It is not that they were not aware that the teaching was going to be demanding,” the authors point out. “However, they feel that the demands of the work exceed their capacity for adaptation. This raises the questions: what can be done to stop this trend? The general response of the government is that education will improve by reducing the workload, eliminating unnecessary tasks and increasing payment. This can help, and our study continues the discourse that the workload is key. However, it also indicates that part of the problem lies in the culture of teaching, constant scrutiny, the need to perform, and hypercritical management. Just reducing the workload will not address these problems. ”
