What is revenge porn?Revenge porn is the intentional sharing of private sexual content, without the consent of the person in that content. It could be explicit text messages, photos or videos, for example. Revenge porn hasn’t been around forever; it has grown with, and been facilitated by, the internet, smartphones and social media.The humiliation and harassment that comes with it can cause severe emotional distress. Both adults and minors are at risk, with younger people often unaware of the dangers posed by internet trolls, cyberbullies and vengeful exes. While it is a relatively recent phenomenon, many countries and regions have brought in legislation against revenge porn. That currently includes all but 4 states in America, despite there being no federal law on the matter.The issue of consent is key here. The person in the photos or videos might well have initially shared the content of their own free will. That’s common between romantic or sexual partners these days. But they almost certainly didn’t agree to the images being shared more widely, which is where it turns into revenge porn. Some have claimed that the term revenge porn is a misnomer, because it suggests the victim did something to provoke the abuse. The most common scenario is a female victim, with the perpetrator being an ex-boyfriend, retaliating out of bitterness at how their relationship ended.But revenge porn is often more about power and intimidation than revenge. We have seen hackers famously obtain intimate photos of celebrities and then leak them on the internet to make a name for themselves. And some offenders simply get a kick out of feeling victims are under their control. They may try to use blackmail for financial gain or to receive more explicit images from the victim. This is known as sextortion.See acast.com/privacy for privacy and opt-out information. Learn more about your ad choices. Visit megaphone.fm/adchoices

What is a sedentary lifestyle?A sedentary lifestyle is one which involves little or no physical activity. It’s one of the major global health issues of the 21st century, as it is an underlying cause of death, disease and disability. It’s estimated that each year over 300,000 premature deaths are caused by obesity and sedentary lifestyles, just in the United States.Screen time spent in front of a computer or TV is often a good indicator of how inactive a person is. When we sit down, our muscles don’t perform the important contractions our bodies need to clear glucose and fats from our blood. This in turn increases the risk of diabetes or heart problems.Generally speaking, you can consider yourself having a sedentary lifestyle if you sit for 7 hours a day or longer. In fact, those who sit for more than 11 hours a day have a 40% higher risk of premature death than those who sit for fewer than 4 hours per day. So simply remaining seated for too long can be a matter of life and death!Humans are increasingly inactive from an early age. A National Household Travel Study found that 54% of children aged 5 - 17 were driven to school in a private vehicle in 2017. Meanwhile, an additional 33% travelled by school bus. You can do the math, that only leaves a small percentage who walk or take public transportation.All the while, American children are averaging 3 hours of screen time per day, which puts them at a greater risk of obesity. On weekends, that figure can rise to between 5 and 7 hours.Staying seated for too long is bad for many health indicators, in the long term too. So it’s better to start off on the front foot. Our cardiorespiratory capacity is at its highest at the end of our teenage years. It then begins to decline from the age of 35. Therefore being fitter from an early age will reduce risks when you get older.Nowadays, inactivity is a bigger killer than tobacco, as it affects a far greater number of people. Having a sedentary lifestyle increases the risk of cardiovascular diseases, obesity, diabetes and high blood pressure.See acast.com/privacy for privacy and opt-out information.

What is CBD?CBD is short for Cannabidiol, which is one of the chemical components found in cannabis. Not being psychoactive, CBD is legal in many countries. But it’s also claimed that CBD has several health benefits. That’s why demand has been growing around the world for a few years now.Cannabis is illegal in most countries, mainly because it contains the psychoactive chemical Tetrahydrocannabinol, or THC for short. But cannabis also contains CBD, which has an almost identical structure to THC, just without causing a high. Furthermore, the greater the quantity of CBD in cannabis, the lower the effect of THC on the brain. That’s because it doesn’t directly trigger the cannabinoid receptors found in our bodies. So CBD is allowed in a lot of places, and it’s been federally legal in the United States since 2018. However, many states have restrictions on which CBD products are allowed. Because there are almost endless possibilities when it comes to potential derived products. We’re talking vape kits, oils, sweets, creams, toothpastes, shampoos and even pet products. The enthusiasm for CBD products is such that expected market growth in the US is 700%. In Europe, dedicated stores are popping up across many major cities. And the clientele age ranges anywhere from 30 to 80 years old.It’s claimed that CBD has a range of medicinal and relaxing benefits. It’s classed as an anti-inflammatory agent, which means it could have a painkilling effect for sufferers of Crohn’s disease. It could also be used to treat psychosis, anxiety or epilepsy. All the same, scientific research is lacking and doctors have a hard time saying what dose of CBD would have positive effects. While that remains blurred, brands and stores are pushing CBD hard, promoting claims about its benefits in all forms, and selling more and more.See acast.com/privacy for privacy and opt-out information.

What is a narcissistic pervert?It seems like we hear about narcissistic perverts pretty often these days. They are charming manipulators who often turn their partners’ or families’ lives into hell. So, are we all surrounded by narcissistic perverts? The term has its origins in psychoanalysis. It was coined in the 1980s and began to get more attention at the start of the 21st century. Narcissus was a mythical figure from ancient Greek times, known for his pride and beauty. He met his demise when gazing into his own reflection in a pool of water. He became so entranced that he ended up drowning without realising what was happening.Narcissistic perverts are characterised as having a negative self-image. They lie to and belittle others in order to increase their own self-esteem. They act like they are better than others, need to be admired and are conscious of their manipulation skills, all the while feeling no empathy when seeing others suffer.More often than not, narcissistic perverts are male. They may cause harm to their romantic partner, but it could also be a work colleague, friend or family member. The causes of this behaviour haven’t been identified, but psychologists believe an overprotected childhood, with high expectations, may be a cause. On the other hand, narcissistic perverts could also have been abused or neglected as children.There’s no need to overreact and fear encountering narcissistic perverts everywhere. The description has become prominent in popular psychology, often discussed in the media. It was also one of the most searched terms on Google in 2019. Nevertheless, they’re not hanging out on every street corner. The term is also not formally recognised in psychiatry, so there are no official figures on how many narcissistic perverts are really out there. But the similar sounding narcissistic personality disorder only affects between 0.5 and 1% of the general population. We might be too quick to label people, when they display one or more character traits which are synonymous with this disorder.See acast.com/privacy for privacy and opt-out information.

What is Flygskam?Flygskam is a Swedish neologism, which literally translates into English as “flight shame”. Confronted with the high level of pollution generated by this form of transport, more and more people are ashamed of travelling by plane. Some are even going as far as boycotting it as a means of transport, a trend which is of course of concern to airlines and plane manufacturers. The word originated in Sweden in 2017, but really entered the mainstream in the English-speaking world a couple of years later. That was largely due to the growing fame and speeches of Greta Thunberg. This shame of travelling by air comes from growing awareness of environmental issues. The Intergovernmental Panel on Climate Change estimates that aviation is responsible for 3.5% of global climate change. They estimate that figure could grow to 5 - 15% by 2050, if action isn’t taken to cut emissions.It’s the wealthy who contribute the most towards air pollution. According to a study by non profit organization The International Council on Clean Transportation, 12% of the American population account for two-thirds of total flights out of the USA. These frequent flyers average 6 or more return journeys per year. Of course, that means they are also responsible for two thirds of the resulting greenhouse gas emissions. Some governments have taken action already, by bringing taxes on kerosene, one of the main aviation fuels. In the European Union, kerosene is currently exempt from taxation but activists are campaigning to revoke that agreement. In the meantime, another solution is to not take the plane at all, opting for shorter-distance journeys which can be made by train.  See acast.com/privacy for privacy and opt-out information.

What is Asperger Syndrome?Asperger Syndrome is an autism spectrum disorder, characterised by difficulties in social interactions and restricted interests. Asperger’s is often diagnosed late, which is why associations run campaigns to increase awareness. International Asperger’s Day is celebrated every year on the 18th of February, to educate the general public and highlight the challenges faced by those with Asperger’s. People living with Asperger Syndrome can have a hard time building friendships or romantic relationships, due to the difficulties they have understanding social conventions. They also have repetitive behaviour and very specific interests.  The syndrome was named after Austrian paediatrician Hans Asperger. As a child, Asperger himself had trouble finding friends and was talented in language. Years later he observed similar traits among child patients in his clinic and published a paper on the findings. Asperger Syndrome came into mainstream consciousness in the 1980s and was added to the umbrella diagnosis of autism spectrum disorder in 2013.Asperger Syndrome is a form of autism, but autism itself is characterised by some intellectual deficit or language learning impairment. That’s not the case with Asperger’s. In fact, people with the syndrome tend to use a relatively sophisticated level of language. They may however struggle to understand metaphors or irony, usually taking things at face value and being very direct. The lives of those with Asperger’s are complicated due to physical clumsiness, as well as hypersensitivity to noise, light and odours. More generally, they can have trouble recognising their own emotions and the emotions of others. They can’t always interpret forms of non-verbal communication like gestures and facial expressions.See acast.com/privacy for privacy and opt-out information. Learn more about your ad choices.

What is the Halo Effect?The Halo Effect is a form of cognitive bias, whereby we base our overall opinion of a person on a single characteristic. It’s most often a positive characteristic, hence the name - it’s as if we see the person as having a halo.The Halo Effect was named in 1920 by American psychologist Edward Thorndike. He carried out an experiment among commanding officers in the military. They had to evaluate their soldiers on a number of physical characteristics and personality traits. The officers tended to associate superior physique with superior intellect, loyalty and leadership. On the other hand, when their perception created a negative aura around a soldier, they could only see negative characteristics. This is known as the “reverse halo effect”, or “horns effect”.Our brains find it hard to accept anything that contradicts our first impression of another person. That rings true even when we are presented with evidence to the contrary. That’s because our minds actively look for information to confirm pre-existing beliefs.The Halo Effect can lead to forms of appearance discrimination in many domains. In the professional world, a physically attractive job hunter may be seen as more intelligent and competent than other candidates, even if it’s not really the case. If a recruiter notices a positive trait in the candidate, they tend to pay less attention to their flaws. The candidate would then have a higher chance of being recruited for a skilled job, as well as greater salary expectations. Being tall is also beneficial in terms of earning more money. According to one study, we earn 300$ more per year for every extra centimetre in height.See acast.com/privacy for privacy and opt-out information. Learn more about your ad choices.

What is a power nap?A power nap is a short sleep which is long enough to give an energy boost, but not so long that you enter deep sleep. The term was coined by American social psychologist James Maas, a professor at Cornell University. Science shows that power naps could be of benefit to employees in the workplace, where efficiency is key.Sometimes, a power nap lasts just a few seconds, in which case it’s referred to as a microsleep. Dali would do it in a seated position, holding a spoon between his fingers. When he started to fall asleep, his grip on the spoon would loosen and the sound of the spoon hitting the floor would of course wake him up immediately. Microsleeps can be experienced in front of our computers, or in public transport, when we are woken by our heads nodding. Power naps supplement regular sleep, in order to maximise its benefits for the body. That’s especially true for those who don’t get enough sleep at night time.The ideal length of a power nap is 15 to 20 minutes. This allows the body enough time to enter a light sleep stage and remain there for at least 2 minutes. It also helps us to feel in good shape for a whole afternoon. Nevertheless, be careful not to go over 30 minutes when napping. Otherwise you may enter a deep sleep phase. That can result in feeling groggy and disoriented when waking up, basically more tired than before starting the nap and wiping out its benefits.For many years, scientists have been studying the benefits of sleep, in the form of both naps and longer length. Tests have been run on a wide range of cognitive processes, generally showing naps to be as beneficial as a full night’s sleep for some memory-related tasks. Other studies have shown the possible impact of napping on our health, in particular reducing the risk of heart attacks and strokes.See acast.com/privacy for privacy and opt-out information.

What is a pension fund?A pension fund is a retirement scheme created by a company or public employer in order to save money for its employees. Belonging to a pension fund may be compulsory or optional. Employees make contributions to the fund, as do employers most of the time. When an employee retires, they can choose to receive a lump sum right away, or a series of regular payments throughout their retirement, like an annuity. That’s how a funded pension scheme works, because the plan has enough assets to pay retirees for the foreseeable future. On the other hand, with unfunded plans, payments are made directly from contributions and no capital is accumulated. The pension fund system first developed in Scotland, with the creation of the “Scottish Widows” scheme in 1815. That insured widows of Scottish soldiers killed during the Napoleonic wars with France. Nowadays, pension funds are particularly common in the United States, but the largest pension fund in the world is Japan’s Government Pension Investment Fund. It was created in 1954 and now manages assets of $1.4 trillion.Pension plans rely on asset management companies to look after the contributions they receive. These companies, generally banks, insurers or specialists, aim to maintain the capital held in the fund and make a profit. American global investment management corporation BlackRock is the number one in the world, with over $7 trillion in assets managed as of the end of 2019.Their activities are strictly regulated. Each country has its own prudential standards. All capital collected must be divided between a number of asset classes. The primary law governing pension plans in the USA is the Employee Retirement Income Security Act of 1974.Some funds are defined benefit pension plans, whereby the pension payment or lump sum is guaranteed. But these are getting rarer and rarer, giving way to defined contribution schemes. This means only the contributions collected are guaranteed.See acast.com/privacy for privacy and opt-out information. Learn more about your ad choices. Visit megaphone.fm/adchoices
