Philomena Bushfield, 120, is a life-long nudist who hasn't "worn more than a pair of socks since I was 7." She is rarely sick, still runs in marathons, and has the energy and enthusiasm of a woman half her age. "It also made it much easier to meet men," says Bushfield, who currently has three different boyfriends.

Liz Sexton, 117, was a strip-tease artist for most of her life. "I was stripping until I was 83," recalls Sexton. "Didn't even need to wear a bra till I was 95." To this day, Sexton wouldn't wear clothing if you paid her. "Your skin can't breathe with all that covering. And besides, I like to feel the cool air whistling over and under my yah-yahs."

A retired Biblical scholar, Beverly McKinnon, 112, took to dressing like the Garden of Eden's Eve early on. "I've found it so comfortable to wear my three strategically-positioned fig leaves," McKinnon says. "It's my connection to the Bible, to man and woman's origin, and to getting a lifetime's worth of appreciative hoots and whistles from the men of my village." McKinnon recently returned from her fourth expedition to climb Mount Everest...

A new research indicates that our ancient human ancestors may have bred with a now extinct species of humanity before migrating from Africa to Eurasia.

Modern humans who are known as Homosapiens are now the only surviving species of humanity while other who once roamed the Earth, made their way out of Africa before humans did.

Recent genetic analysis of fossils from other ancient human species, such as Neanderthals in West Asia and Europe and the Denisovans in East Asia, have revealed that they once interbred with Homosapiens, giving modern humans genetic mutations that protected them as they began expanding across the globe about 65,000 years ago...

Some stimuli will invoke a huge, quick response, and others a smaller, yet longer, extended response. There is a varying degree of neurotransmitter release depending on the strength of the stimulus, as well as how long we are in the presence of it. Remember last time - I told you that the longer you interface with a stimulus, or the more time you spend interacting with it, the greater attachment you will form to it.

Some studies have looked at the different types of sex and the variable neurochemical responses based on the type of sex the person is engaging in. However, it is probably not the case that the penis causes more dopamine to be released than a vibrator, for example. More likely, it is the state of mind the person is in that really has an effect on the amount of pleasure he or she is experiencing.

The cognitive state of the brain at any given moment in time is what causes the release of dopamine, whether it is prompted by a physical or a mental stimulus. Can the brain be stimulated via tactile nerve pathways to release large amounts of dopamine? Sure. However, consider this: You can give one person two separate, yet identical patterns of physiological stimulation, and end up getting radically different subjective experiences as a result. This implies that it is not just the physical act of sex that gives us so much pleasure, but how we represent that act in our mind that really has impact...

Wenner’s story goes beyond saying porn is safe. It suggests that it might actually be beneficial. I am not sure I buy this, but some coincidences worth mentioning back up this view. First, as access to Internet pornography grew in this country, rates of rapes and sexual assault went in the opposite direction. Those stats are at their lowest levels since the 1960s. And something similar happened in Japan, China and Denmark. Along those lines, the U.S. states in which rapes rose by 53 percent had the least Internet access between 1980 and 2000—and so the least access to Internet porn. States with the most access saw a 27 percent drop in reported rapes...
