Hormones and Qualities Lives

Author: Steven F. Hotze

Publisher: Forrest Publishing (April, 2016)

Dr Steven Hotze is leading a wellness revolution that advances a new model of healthcare. Unlike the popular medical way of treating individual symptoms(症状) with the familiar “anti” drugs, Dr Hotze deals with the basic causes of poor health.

In Hormones, Health, and Happiness you are shown how to reach and keep the best body functioning.

Based on a process of biologically the same hormones(荷尔蒙) and other natural treatments, it can help you enjoy a better quality of life.

    Most of us will be familiar with the traditional talent show set-up: thousands of hopefuls line up outside the audition（试音）room, wait for hours to go in and perform for a group of judges. Then these potential pop stars could be lucky and get through to the next round, or they might hear the command, "Sorry, it's a no from me. But what do the judges actually bring to a talent show?

    Music talent show judges attract millions of viewers each week to their programs. As public figures, they play an important part in advertising campaigns for these programs. They often receive high salaries and can be moody. Are they really worth the expenses and difficulties that they cause? One solution might be to replace them with computers.

    Can computers really match human judges? Scientist Dr Nick Collins and his team at the University of Sussex think they can. Dr Collins has been working on a project that involves programming three computerized judges that he says would be far more consistent in their judgment of musical performances. Employing a special programming language, Dr Collins's digital judges can be trained up by "listening" to particular musical styles. After they have been listening for a while, the programming language allows these judges to spot the specific features of the music, including the voice quality, the rhythm etc. Collins says, “The judges' listening capacity is not yet as good as a human ear, but they won't be as moody as some human reality TV show judges.”

    Maybe that is the problem with this electronic musical innovation. Real human judges on talent shows interest us with their personality, decisions and catchy phrases. Will a computer program be able to do the same?

    Cao Yuan, a PhD student from China, had two papers published on strange behaviour in atom-thick layers of carbon that have opened up a new field of physics.

    Pablo Jarillo-Herrero's group at MIT was already layering and rotating (旋转) sheets of carbon at different angles when Cao joined the lab in 2014. Cao's job was to find out what happened when one graphene (石墨烯) sheet was twisted only slightly wiht respect to the other, which one theory predicted would thoroughly change the material's behaviour.

    Many physicists doubted the idea. But when Cao set out to create the subtly twisted stacks, he spotted something strange. Exposed to a small electric field and cooled to 1.7 degrees above absolute zero, the graphene—which ordinarily conducts electricity—became an insulator. That by itself was surprising. But the best was yet to come: with a slight change to the field, the twisted sheets became a superconductor, in which electricity flowed without resistance.

    The ability to get atom-thick carbon into a complex electronic state through a simple rotation now has physics demanding to engineer exciting behavior in other twisted 2D materials. Some even hope that graphene could shed light on how more-complex materials superconduct at much higher temperatures. "There are so many things we can do," says Cory Dean, a physicist at Columbia University. "The opportunities at hand now are almost irresistible."

    Hitting graphene's “magic angle”—a rotation between parallel sheets of around 1.1°—involved some trial and error, but Cao was soon able to do it reliably. His experimental skill was extremely important, says his supervisor Jarillo-Herrero. Cao pioneered a method of tearing a single sheet of graphene so that he could create a stack of two layers, from which he could then fine-tune alignment (微调校准).

    Cao loves to take things apart and rebuild them. A heart, he is “a tinkerer”, his supervisor says. On his own time, this means photographing the night sky using homemade cameras and telescopes—pieces of which usually lie across Cao's office. "Every ime I go in, it's a huge mess, with computers taken apart and pieces of telescope all over his desk," says Jarillo-Herrero.

    Black Friday

    The day after Thanksgiving is the start of the holiday shopping season. Thanksgiving is always on a Thursday, so the day after is a Friday. This day has come to be known as Black Friday. It has been the busiest shopping day of the year since 2005.

    Most stores offer great deals on Black Friday. They open their doors in the small hours of the morning. They try to attract shoppers with big discounts. Some items like TVs are much cheaper than usual. Stores may even lose money on these items. They hope that shoppers will buy gifts for other people while they are in the store.

    Black Friday is a great time to get good deals. The problem is that there are not enough low-priced items to go around. Each store may only have a few. These items are in high demand. People stand in long lines to get such great deals. They may line up hours before a store opens. They may be hoping to get a low price on a TV or laptop, but not everyone who wants one will get one. Some people leave disappointed.

    The situation can be tense(紧张的). Some Black Friday events have been violent. Large, eager crowds have trampled(践踏) workers. Fights have broken out over toys or people cutting in line. People have shot one another over parking spots. But most Black Friday events are safe and fun. Still, if you plan on going, expect large crowds and a bit of pushing and shoving.

    So where does the name "Black Friday" come from? It was first used in Philadelphia in the 1950s. The police called this day Black Friday because of the heavy traffic it drew. In the 1960s, spread across the country. It seems that it is here to stay.

    Now people all over the country take part in the event known as Black Friday. It is even spreading to other parts of the world. Stores have held Black Friday events in the U.K., Australia, and Brazil since 2012. In Costa Rica Black Friday is known as "Viernes Negro." And in Mexico, stores offer an annual weekend of discounts. They call it "El Buen Fin," which means "the good weekend" in Spanish. I guess the language of savings is universal.

    Over the next decade, technology will decimate more jobs in many professions.

    Some robots already cost less to operate than the salaries of the humans they replace, and they are getting cheaper. Boston Consulting Group predicts that, by 2025, the operating cost of a robot that does welding (焊接) will be less than $2 per hour, for example. That's more affordable than the $25 per hour that a human welder earns today in America.

    Uber and many other companies are working on developing cars and trucks that don't need a driver in the driver's seat. According to the American Trucking Associations, approximately 3 million truck drivers were employed in the United States in 2010, and 6. 8 million others were employed in other jobs relating to trucking activity. So roughly one of every 15 workers in the country is employed in the trucking business. We could be talking about millions of jobs disappearing in the early 2020s.

    And then there is the "Gig Economy (零工经济)" that has some businesses moving toward part-time, on-demand employment. Uber has already done this to taxi drivers, and other technology companies are doing it to a wide range of jobs. A study by Intuit predicted that, by 2020, 40% of American workers will be self-employed, and that full-time jobs will be harder to find. We are talking about 60 million people in this category. The problem is that not only do such part-time workers lack reliable full-time jobs and sick pay, but they can't enjoy health insurance and longer-term benefits.

    The measures to be taken are to raise trade barriers. But closing the doors to foreign trade won't bring jobs back. It will only slow the global economy and hurt American exports, shrinking the U. S. economy and accelerating job loss.

    A headache is the feeling you get when your head hurts. Headaches can differ from very mild to incredibly powerful. They can last anywhere from 10 minutes to hours. Very bad headaches are called migraines. People who suffer from migraine headaches often need to take the day off from school or work and lie in bed all day.

    Why do people get headaches? There are many possible causes. People who drink too much caffeine (in coffee or soft drinks, for example) or alcohol can end up with headaches. This is because these kinds of drinks take water away from the body. If the brain doesn't have enough water, it gets smaller and pulls away from the head. This can be extremely painful. The best way to get rid of this kind of headache is just to drink lots of water.

    Tension headaches happen when the body's muscles are too tight. When people feel stress, it is common for the muscles near the head to become tense. Tension headaches might also be caused by not getting enough sleep. Some people suffer from tension headaches for only short times but for other people, these kinds of headaches are a chronic problem that happens again and again. A massage (按摩) might help to stop a tension headache. If that doesn't help, you might need to see a doctor.

    Headaches can also be caused by much bigger health problems. For example, a head or neck injury can cause them. Headaches can also be a warming sign of a heart attack.
