The Rare Truth About Sexual Compulsivity
Today we have a tiny number of true sexual compulsives who do things like getting repeatedly arrested for public masturbation. We also have a large number who fear or believe or have been told they’re sex addicts. But oddly, when surveyed about what purported addicts actually do sexually, they don’t have any more sex or any wilder, less controlled sex than boatloads of people who feel certain they’re psychologically fine.
Many women cannot fathom why so many men feel such a deep need to polish pipe. Many also believe that only evil men watch porn. Actually, almost every man has and does. Canadian researchers wanted to compare sexual attitudes among men who had and had never watched porn. They couldn’t find a single adult man who hadn’t—not one.
Porn is not evil. It’s a cartoon version of men’s fantasies of effortless sexual abundance. Virtually every Internet-connected man on Earth has seen porn, many frequently, some daily or more.
What Happens To Your Brain When You Get Turned On, According To Experts
Getting turned on refers to a physiological reaction we have to stimuli that gets us mentally and physically prepared for sex. Quite literally, it's like turning on a light switch — where there was darkness is light now. Where there was nothing, there is sensation now. While there are some obvious indicators, what actually happens to your brain when you get turned on is not likely something many of us put much thought into. But honestly, you should, because it's fascinating, and sexy.
‘There’s something terribly wrong’: Americans are dying young at alarming rates
Death rates from suicide, drug overdoses, liver disease and dozens of other causes have been rising over the past decade for young and middle-aged adults, driving down overall life expectancy in the United States for three consecutive years, according to a strikingly bleak study published Tuesday that looked at the past six decades of mortality data.
Men, overall, have higher all-cause mortality than women, but the report pulls out some disturbing trends. Women are succumbing to diseases once far more common among men, even as men continue to die in greater absolute numbers.
Millennials Will Get Sick and Die Faster Than the Previous Generation
Wednesday morning, Blue Cross Blue Shield published a 32-page report detailing the myriad ways in which millennials (my cohort!!!) will see their health decline and healthcare costs skyrocket over the next 10 years. The entire thing is a delight to read, and paired very well with my usual morning routine of “staring into my coffee and thinking about how fleeting life is :).”
In the report’s intro, analysts from Moody’s Analytics write that, in examining “millennial health patterns,” they found “several interesting and concerning findings.” Well… Pardon mon Francais, but I’ll freaking say so! Using a combination of data from Blue Cross Blue Shield, the CDC, and prior health studies, the report predicts millennials will achieve the new triple threat of being sicker, broker, and dying younger than the previous generation, Gen X. My fellow millennials have been essentially predicting this very outcome for years, just without all the fancy data, regularly joking that our parents will outlive us. Turns out…...we’ve been right the whole time!
Much of the research examining identity has focused on traits or dynamics that are considered universal for all human beings (e.g., self-esteem, introversion-extraversion, and levels of anxiety) regardless of race, culture, gender, sexual orientation, or class. At this level, researchers and clinicians treat human experiences as being similar, for example, the experiences of aging, coping with life stress, and interpersonal relationships. However, the extent to which any one of these traits and dynamics may be high or low, prominent, amplified, or muted differs as a result of sociodemographic categories such as culture, class, gender, ethnicity, or sexual orientation.
Identity, Self-Esteem and Self-Compassion
Will There Ever Be a Cure for Addiction?
From drinking hand-sanitizing gels to using synthetic marijuana, our society is constantly inventing new ways to get high. When one substance is banned, another quickly takes its place. What drives this never-ending hunt for the next high?
One important motivator is the pleasure principle. The quest for pleasure is a fundamental part of being human. It helps us meet our basic needs by pushing us to work towards specific goals.
Drugs provide an instant shortcut to our brain’s pleasure center. They flood our brains with dopamine and condition us to seek the next high. As a result, our bodies begin reducing their natural dopamine output. With repeated drug use, pleasure dissipates but the cravings remain. Thus, drugs hijack our natural drive for pleasure. Addicts pursue drugs despite the fact that the pleasure they experience from them progressively diminishes.
Humans Can Reverse Their Biological Age, Shows a 'Curious Case' Study
In a small, 1-year clinical trial published Thursday in the journal Aging Cell, nine participants took three common medications — growth hormone and two diabetes drugs — and reversed their biological age by 2-and-a-half years on average. Greg Fahy, Ph.D., lead author of the study and chief science officer of anti-aging therapeutics company Intervene Immune, tells Inverse that this research proves the concept that biological aging may not be unstoppable.
“One of the lessons that we can draw from the study is that aging is not necessarily something that is beyond our control,” he says. “In fact it seems that aging is largely controlled by biological processes that we may be able to influence.”
New study finds vegetarianism and veganism could lead to higher risk of stroke
If you were considering swearing off meat for health reasons, maybe don't throw away that bacon cheeseburger just yet. At least not if all that you're trying to prevent is a stroke. A report by researchers at Oxford published in the British Medical Journal found that out of nearly 50,000 people studied, vegetarians and vegans had a 20 percent higher rate of stroke than meat eaters.
MONSTER HYBRID TUMBLEWEED SPECIES IS TAKING OVER CALIFORNIA, SCIENTISTS WARN
A new invasive species of tumbleweed that can grow up to six feet in height is taking over parts of California—and scientists are warning it could spread even further as climate change makes its growing conditions more favorable.
Salsola ryanii was first identified in California in 2002. It is a hybrid made up of two other invasive species—Salsola tragus, which is native to Russia and China, and Salsola australis, from Australia and South Africa. The latter, scientists say, is "one of the world's worst weeds" and is currently found in 48 U.S. states. The new species, is however, far bigger and faster growing than its parents, reaching about six feet in height.
A tumbleweed is a plant that breaks away from its roots towards the end of summer. It is blown around by the wind—its means of seed dispersal. In doing this, tumbleweeds cause huge problems. They can lead to traffic accidents and damage property. Invasive species also cause problems for the agriculture industry and native ecosystems.
Cyborgs will replace humans and remake the world, James Lovelock says
For tens of thousands of years, humans have reigned as our planet's only intelligent, self-aware species. But the rise of intelligent machines means that could change soon, perhaps in our own lifetimes. Not long after that, Homo sapiens could vanish from Earth entirely.
That’s the jarring message of a new book by James Lovelock, the famed British environmentalist and futurist. “Our supremacy as the prime understanders of the cosmos is rapidly coming to end,” he says in the book, "Novacene." “The understanders of the future will not be humans but what I choose to call ‘cyborgs’ that will have designed and built themselves.”
Tree-planting projects may not be so green
Brides and grooms do it. Transatlantic travellers do it. And you might even be getting it for Christmas. Neutralising your carbon emissions is becoming the must-do activity for the eco-conscious citizen. But now an international team of scientists has raised an unexpected objection: some tree-planting projects may, they suggest, be doing more harm than good.
Carbon offsetting allows people to pay someone else to atone for their climate sins by soaking up the CO2 that they produce. And with the consequences of global warming becoming more apparent, more Britons are opting to undo their personal share of the damage.
Last year companies and individuals in the UK spent around £4m offsetting carbon emissions. The Kyoto protocol allows member countries to do the same through carbon trading.
But it seems the guilt-free option is not as simple as writing a cheque and leaving it to someone else to sort out. Researchers have found that planting trees to soak up carbon can have detrimental knock on effects. "I believe we haven't thought through the consequences of this," says team-member Robert Jackson at Duke University in North Carolina, "I think the policy could backfire on us, but it will take decades to play out."
Study shows social media may harm teens' mental health

The bald facts about diet: to avoid hair loss, you need meat
"Eating a healthy, balanced diet and avoiding excessive stress, extreme diets and fast weight loss are vital in maintaining healthy hair growth," says Lisa Caddy, a certified trichologist with Philip Kingsley, a leading authority in hair and scalp health from London.
The irony: what many people think of as a healthy diet - that is, mainly consisting of fruit and vegetables, with minimal protein and calories - often doesn't include all the elements needed for optimum hair growth, Caddy says.
To function at their best, the cells in the hair and throughout the body need a balance of proteins, complex carbohydrates, iron, vitamins and minerals.
Meats, especially red meats, are particularly important because they're the richest sources of ferritin, a stored iron that helps the body produce hair cell protein.
Here's what happens to your body when you cut out dairy
Making any change to your diet, whether large or small, can be nerve-wracking. When your body has become so accustomed to consuming and digesting a product, it can be concerning to completely eliminate it. One product that more and more people seem to be cutting out is dairy.
Whether you want to cut out dairy for ethical reasons, because consuming it doesn't make your body feel great anymore, or because you've seen it have a positive impact on others — such as with celebrity Khloe Kardashian who credits the elimination of dairy for part of her weight loss— this could be a great choice for you. There's a lot you need to consider, however, before you make the leap, including how your body could react.
Here's what could happen to your body if you cut our dairy.
Why Drinking Water All Day Long Is Not the Best Way to Stay Hydrated
Water is cheap and healthy. And drinking H2O is an effective way for most people to stay hydrated. The National Academy of Medicine recommends that adult women and men drink at least 91 and 125 ounces of water a day, respectively. (For context, one gallon is 128 fluid ounces.) But pounding large quantities of water morning, noon and night may not be the best or most efficient way to meet the body’s hydration requirements.
“If you’re drinking water and then, within two hours, your urine output is really high and [your urine] is clear, that means the water is not staying in well,” says David Nieman, a professor of public health at Appalachian State University and director of the Human Performance Lab at the North Carolina Research Campus. Nieman says plain water has a tendency to slip right through the human digestive system when not accompanied by food or nutrients. This is especially true when people drink large volumes of water on an empty stomach. “There’s no virtue to that kind of consumption,” he says.
