Women are friendly. They often share with others. But men are more competitive. They are trying to improve their social status. Why? Researchers have found it's all due to the hormone oxytocin (荷尔蒙催生素). Although known as the love hormone, it affects the sexes differently.

    Generally, people believe that the hormone oxytocin is let out in our body in various social situations and our body creates a large amount of it when falling in love or giving birth.

    But in a former experiment Professor Ryan found that the hormone is also let out in our body during a negative situation such as envy (嫉妒).

    Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relations, but in women it raises the ability to recognize friendship.

    Professor Ryan's recent experiment used 62 men and women aged 20 to 37.

    Half of the participants (参与者) received oxytocin. The other half received placebo (安慰剂).

    After a week, the two groups switched with participants. They went through the same steps with the other material.

    Following each treatment, they were shown some video pictures with different social behavior. Then they were asked to analyze the relations by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions.

    The results showed that, after treatment with oxytocin, men's ability to correctly recognize competitive relations improved, but in women it was the ability to correctly recognize friendship that got better.

    Professor Ryan thus concluded, “Our experiment proves that the hormone oxytocin can raise people's abilities to better tell apart different social behaviors.”

    They say that an apple a day keeps the doctor away. Well, there is one lady who believes that it's actually chocolate. At 102 years of age, she's living proof.

    According to Boonville, Indiana's Eunice Modlin, a daily dose of chocolate has been the key to a long and healthy life. Specifically, two pieces of dark chocolate. It's not just Eunice who believes this.

    Many scientists have attributed the sweet to health benefits such as lower chances of cancer, cardiovascular disease, and diabetes.

    However, researchers believe that Eunice might be overlooking the fact that she has never smoked or drunk alcohol in her long life, and that chocolate might not be the significant cause of her longevity.

    "There are so many other factors to her long life and chocolate isn't the only one," nutritionist Vanessa Rissetto said. "Genes, her diet in general…are probably the main reasons."

    At any rate, Eunice is still alive and kicking. With four children, seven grandkids, 14 great-grandkids and 11 great-great grandkids, this lady has a big family.

    It must be noted that Eunice was also very athletic, being an archer in her 20s .Amazingly, she has lived through tough times such as the Great Depression and World War II .Also, the healthy blood runs through the veins of other family members. Eunice's brother is also still alive, at 101 years of age.

    No matter what you might think, Eunice's consumption of chocolate can't be ignored. In 2015, a BMJ study showed that a daily treat of one small bar would give the consumer 23% less chance of having a stroke (中风).

    What is in the sweet that makes it so beneficial? Apparently, cocoa beans have flavonoids, plant nutrients that have useful antioxidants (抗氧化剂).

    "Not all chocolate is created equal," Rissetto warns. "Dark chocolate has more flavonoids than milk chocolate, and white chocolate—which does not actually contain chocolate—is not a good source of flavonoids."

Climbing, I once thought, was a very manly activity, but as I found my way into this activity, I came to see that something quite different happens on the rock.

Like wild swimming, rock climbing involves you into the landscape. On the rock, I am fully focused. Eyes pay close attention, ears are alert, and hands move across the surface. Unlike walking, where I could happily wander about absent-mindedly, in climbing, attentive observation is essential.

As an arts student studying English literature, I discovered a new type of reading from outdoor climbing. Going out on to the crags (悬崖), I saw how you could learn to read the rocks and develop a vocabulary of physical movements. Good climbers knew how to adjust their bodies on to the stone. Watching them, I wanted to possess that skillful "language".

My progress happened when I worked for the Caingorms National Park Authority.Guiding my explorations into this strange new landscape was Nan Shepherd, a lady too. Unlike the goal-directed mindset of many mountaineers, she is not concerned with peaks or personal achievement. Shepherd sees the mountain as a total environment and she celebrates the Caingorms as a place alive with plants, rocks, animals and elements. Through her generous spirit and my own curiosity, I saw that rock climbing need not be a process of testing oneself against anything. Rather, the intensity of focus could develop a person into another way of being.

Spending so much time in high and st ony places has transformed my view on the world and our place in it. I have come into physical contact with processes that go way beyond the everyday. Working with gravity, geology (地质学), rhythms of weather and deep time, I gain an actual relationship with the earth. This bond lies at the heart of my passion for rock climbing. I return to the rocks, because this is where I feel in contact with our land.
