Trim yourself.

Know your family history

Clark gable, a Hollywood star and great seducer, didn't just trim his moustache. He trimmed his chest hair and armpit hair. The newspaper said that any curly hair would not damage his perfect figure.

Nowadays, many screen action stars are learning Gaby's method, although for a time, waxing-this method is to apply hot wax to places with hair, and when they harden, they suddenly fall off like a splint, and the hair falls off with the wax-is a more popular method than trimming. Beverly Hill's high-end beauty salons admit that they can even shave his chest hair with an electric razor according to customers' requirements. Professional bodybuilders, on the other hand, make no secret of the fact that they will shave off their hard-won curly hair without hesitation.

"There are two kinds of hair, one is a thin layer of colorless fluff, and the other is thicker, longer and colored hair." Tobmeya, MD, a clinical professor of facial plastic surgery at the University of Southern California in Los Angeles and a collaborator with the Beverly Hills Institute of Aesthetic Plastic Surgery, went on to say, "How much hair we have, how fast they grow and where they grow are all determined by our genes."

The fermentation of most terminal hairs, unlike hair follicles on the scalp and brow bones, only produces short and curly hair. Hair rarely exceeds 1-2 inches before it falls off and is replaced with a new one. This also explains why-for example, your chest hair can't stay long enough to flow to your shoulders, which is why doctors won't transplant hair follicles from your chest, groin or back to your scalp when your head starts to lose hair and go bald.

Improved body hair

Most of us don't care much about our body hair, which is normal. Because when it comes to body hair, it is not just a medical problem-women have various views on it. But from an aesthetic point of view, we should at least not let our hair stick out of our nostrils or ears. Similarly, we don't want to grow a third eyebrow between our two eyebrows. Hair seems to grow where we want it.

"Do you feel uneasy because you have a lot of body hair? Rent a DVD of robin williams and watch him take off his shirt. You'll feel much better. Do you still want to take action? In the past, hairdressers even shaved off some body hair as part of a haircut. However, now such things have to be done by ourselves. " Christina Grafasi, head of the hair department of a high-end beauty salon in Manati, new york, told us this.

Greefacie added: "You can go to department stores to buy decorative scissors with dome-shaped safety handles and less sharp knives, electric razors and electric nose hair razors. They will give you a lot of help. "

Ms. Greefacie suggested that long nose hair can be trimmed with an electric nose hair razor and trimming scissors. As for electric shavers, especially those without any special accessories, they are very suitable for shaving hair protruding from ears and eyes.

As for the treatment of the hair around the ear, we can accept the suggestion of Dr. John Romano, a dermatologist and clinical professor at new york Hospital of Cornell Medical Center in new york: shave it off. Before shaving, wet your ears and then shave gently on the earlobe.

It is both costly and time-consuming to permanently remove hair and pain with electroacupuncture. Professionals connect the needle to the current, completely destroying the hair roots. This operation requires many visits and costs about $ 60- 100 per hour to completely destroy the hair roots. The brain has been thinking. Thinking is the way for the brain to exercise and absorb the nutrients it needs: regularly exercise vitamin B6, boron and zinc to keep the blood circulation smooth.

Since the industrial revolution broke out in the early19th century and entered the stage of rapid development and scientific saving the world, medicine has developed in all directions. People study microorganisms and embryos, bacteria and birds, spores and monkeys. Almost everything is cut into small slices and studied under a microscope.

The opportunity came, and people even began to study the human brain. Some organizations, such as an autopsy association in Paris, try to examine the left hemisphere of some outstanding people's brains. After getting one, they will weigh and measure the volume, hoping to find out some relationship between brain volume and human intelligence.

What they found was an ancient and immortal fact: big is not always good. Napoléon Bonaparte's nephew Charles Louis Napolé on Bonaparte has a huge brain weighing150g, which is 17% larger than that of the famous poet walt whitman. (After weighing, an unknown member of the American Anthropometry Association threw Whitman's brain to the ground, and it was smashed to pieces, making it impossible to continue research. ) The tyrant Ludwig has a brain weighing1.349g under the thick Bavarian skull, which is 10% larger than that of Albert Einstein, the famous inventor of relativity. Unfortunately, abraham lincoln's brain capacity is not recorded in history. Perhaps, as some historians have said, he lost part of his brain when he was assassinated, or scientists were embarrassed to find that such a prestigious person had such a big brain.

What does all this mean? There is no need to be jealous of the neighbor's skull! If you give your brain proper nutrition and enough thinking stimulation, and you often do physical exercise, then no matter how big your brain is, it can work for you efficiently for decades.

"People usually think that they can't do anything for their brains," said Dr. Douglas Herman, a memory researcher at the National Center for Health Statistics in Maryland and the author of Super Memory. "This is wrong. Nutrition and other factors can improve memory and other brain functions. As long as you do it, it will have an effect. "

Functional distribution of human brain

The brain is the terminal of the central nervous system. It gets current stimulation from nerve endings all over the body, sorts out the information expressed by the body, and then returns the information to the neural network, giving instructions to the body: bending over, sneezing, sweating and so on.

Of course, the brain does much more than that. It also has some advanced functions such as language, creativity and logical thinking. It can store information (memory). It can understand the stimulation from the eyes, so you can see objects. All this is done through this "small bag" weighing about 3 pounds and fixed in your skull.

The brain can be divided into many interrelated parts, and each part controls different functions of the body accordingly. The brain hemisphere is the largest part, which embodies the basic characteristics of people, such as reasoning and reason. Most of these functions are undertaken by a part of the cerebral hemisphere, namely the gray cerebral cortex covering the outer hemisphere. The cerebral cortex receives information from the nerves of the whole body and directly directs body movements, such as bending fingers and walking. This is also the place to understand sensory stimuli: it receives information from eyes, ears, nose, tongue and skin, and distinguishes color, sound, taste, smell and touch. The cerebral cortex can also store memory information, and most of the information of the brain is stored here.

The average brain has 654.38+000 billion neurons. In order to prevent aging, some functions of the brain will inevitably degenerate. Exercise your brain (by thinking) when you are old. Read, do crossword puzzles, etc ), invest enough vitamin B6 and exercise regularly.

There is thalamus deep under the cerebral cortex. This is equivalent to the distribution center of the brain, which sends all kinds of information to the corresponding parts of the thigh cortex according to its sensory circuits. In fact, the thalamus can be said to be a variant of the cerebral cortex, but it is like a mute. For example, it can feel pain, but it can't tell the difference between the pain cut by a paper cutter and the pain sawed by a coarse-toothed saw.

There is also a bundle-like peripheral system under it, which is where our deepest and most secret feelings lie. Although the peripheral system is absorbed from Latin, which means the periphery and peripheral interface of a system, it actually manages many activities in our daily life, such as digestion, heartbeat, and many other feelings and behaviors.

Other parts of the brain manage some activities like mammals. The brain controls the activities of the heart, blood vessels and respiratory system. Hypothalamus is located in the lower part of the brain, which controls the body's metabolism, body temperature, blood sugar level, stomach and sexual sensation. The cerebellum arranges muscle activity. When the cerebral cortex sends out a movement instruction, the cerebellum will tell which muscle to move and how to move.

Mental consumption

The average human brain contains about 654.38+000 billion nerve cells, and each nerve cell has several small branches, called neuron dendrites, which are used to communicate with other nerve cells. The points where these dendrites contact are called synapses of neurons. If each nerve cell keeps in touch with 10 cells (this is still a conservative estimate), it means that only in the cells of the brain, each contact can reach 1 trillion times, and theoretically the possibility of contact is infinite.

This seems to far exceed the number we need in our lifetime. But time and other factors will make them suffer. When we enter middle age, we begin to lose a large number of neurons (neurons are nerve cells that transmit signals to each other) and another nerve cell that helps and fixes neurons.

The brain will not produce new neurons to replace the lost ones. In this way, after a long time, it will gradually form a greater impact. We gradually lose neurons in the brain stem, which will affect our motor skills. This means that our movement slows down, we lose flexibility and it becomes difficult to walk. Neurons in the cerebral cortex may also rupture or die, which will affect our learning, memory and other advanced functions.

Obviously, the brain tries to compensate for the loss of neurons by re-strengthening and establishing new connections between surviving neurons. The rate of neuron loss increases with age. At this time, the brain needs more time to recover its memory, and it can't finish what it has done as quickly as it did when it was young.

This does not mean that you have been diagnosed with Alzheimer's disease. Dr. Herman said that unless you have a brain disease such as Alzheimer's disease or a severe stroke, your brain can still work efficiently in old age.

Dr Herman takes a computer as an example to illustrate this problem: when you are young, you have a "Pentium" speed brain, which can perform quick calculations and quickly restore your memory. When you get old, maybe your brain is more like a 386 computer. It is not so fast in processing and storing information, but it is still fully qualified for the job.

Just like a supercomputer, the brain needs regular maintenance to keep its sensitivity. Here are some suggestions on how to maintain it:

Vitamins will be of great help. Dr. Herman said that vitamins help the body to produce the conduction force of the nervous system, so that brain cells can constantly transmit information to each other. A study of 38 elderly Germans showed that taking 20 milligrams of vitamins every day can help to strengthen long-term memory. The normal daily requirement of vitamins is only 2 mg per person, but it is still within the safe range for mg. There is a better way: the nutrition of the diet should be balanced and contain more fruits and vegetables. Frozen or processed vegetables may lose 15%-70% vitamin content, so it is best to choose fresh vegetables. Other foods rich in vitamins include chicken, fish and lean pork.

Coordinating physical exercise between muscles and brain will promote brain health. Research shows that regular aerobic training can improve your ability to do many things at the same time and develop your creativity. Doctors don't fully understand why this happens, but they think that because physical exercise enhances cardiovascular function, the brain can get more oxygen and other nutrients from the blood, and even get more blood flow.

Use it or lose it. When you use the brain, the cerebral cortex will bend. The researchers found that people who have a college degree and keep their brains active all their lives have 40% more dendrites than people with low education and less challenges.

You really don't need a diploma to improve your dendrites. Dr. K. Gunney Schell, a professor of anthropology at Pennsylvania State University, suggested that all kinds of mental activities can keep the connection between your brain cells strong. So you should take part in continuing education in local universities as much as possible, or at least take part in TV education courses.

Mental activity can even help ward off Alzheimer's disease. A study by Columbia University in new york shows that people with higher education and great achievements in their work are only 1/3 more likely to develop Alzheimer's disease than others. This is probably because these people who often use their brains better protect synapses. This means that when Alzheimer's disease strikes, the communication between their brain cells is less interrupted.

Maintaining low blood pressure and high blood pressure will have many consequences. About 40% of cerebral hemorrhage is related to hypertension. Hypertension can slow down thinking, dull people and damage short-term memory. Worst of all, a study of 35 men aged 5 1-80 showed that hypertension can lead to permanent changes in brain structure and tissue loss. Beth Raismes, a psychiatrist, a senior lecturer and a doctor of medicine in a hospital in Kent, England, said that after a period of time, there will be obstacles in language, memory and direction recognition.

The authoritative suggestion is to measure blood pressure every three years and every two years after 40 years old. This kind of examination is so simple that you can even check your blood pressure at every physical examination.

Avoiding boron deficiency Maybe for some people, they only need a few handfuls of peanuts to achieve intellectual development. James Pelaes, a psychologist at the Grand Fox Human Nutrition Research Center of the United States Department of Agriculture in North Dakota, asserted. Trace element boron is very beneficial to people's memory, attention and motor skills. Studies show that a group of people who consume 3.25 mg of boron every day scored significantly higher in these three groups of tests than a group of people who had less greenhouse elements in their food. The greenhouse is rich in peanuts. Peanuts contain about 0.5 mg boron per ounce. However, it should be noted that peanuts have high oil content and sufficient calories. Other foods that provide a rich shed include preserved plums, dates and raisins. "We have about 0.5 mg per ounce, honey and a shed of 0.2 mg per ounce.

Don't forget zinc When you think about trace elements in your body, don't forget zinc. This memory-aiding element can improve the function of neurons. Shrimp has the highest zinc content, 8.2 mg per half cup (1/4 pint); Roast lean beef, a 3-ounce serving contains about 5.3 mg; Lean pork, 3 ounces each containing about 3.2 mg; Boil dried beans, about 1.8 mg per cup; Lima beans, 0.7 mg per half cup; Experts don't remind people to supplement zinc, because too much zinc in the body can cause serious dysentery, nausea, vomiting and even arteriosclerosis.

Put less waves when making white rolls.

Carbohydrate is essential for marathon runners, but research by Harvard University shows that eating foods with more protein content is more conducive to sprinting. If a man over 40 eats sorbet composed of 65,438+0,000% carbohydrates, it is almost twice as difficult for him to concentrate and do other mental work as a turkey eater. Bonnie J. Spring, a professor of psychology at Health Science University and Chicago Medical College, believes that this may be because carbohydrates raise some serum in the brain and have hypnotic effects. On the contrary, foods containing more protein, such as turkey, fish and chicken, contain tyrosine, which has been proved to make people think clearly and keep their brains awake.

Carbohydrate is the main source of hot dishes in any food, but if you want to keep a clear head for the next few hours, you can choose food that lacks protein.

Have a drink: You did the right thing to forget something.

Ethanol can kill brain cells at will, and after a long time, it will also lead to memory loss and muscle atrophy. No one has ever given a "safe" amount of alcohol. However, a recent study in Finland pointed out that drinking 32 ounces of beer, 2 ounces of wine or 0.5 ounces of spirits will gradually destroy brain cells after a period of time. Dr Herman said; A glass of beer or mixed drinks a week, drunk in moderation, will hardly cause any trouble.

Martinis also have some minor problems. Dr Herman said that acetic acid can affect your concentration, so when you feel a little dizzy, you are less likely to concentrate on conversation or other details. This means that you may hardly remember these conversations and details the next day.

You don't have to take medicine-that's stupid.

Maybe you have seen pills or powders like "brain-strengthening cocktails" in magazine advertisements, claiming that they can strengthen the brain. But please note: a beautiful pill may mean a stupid mistake. "The best advice I can give you is never to be confused by them," Dr. Herman said. "You may have an allergic reaction to them, and maybe they will interfere with the effects of other drugs you take." In addition, he said, we don't really know whether the glucose, lecithin, selenium, amino acids and other ingredients contained in the drugs they claim will work as they say. "It may be effective in a few years, but it may never be," he said.

The price we pay &

Complex things often need to pay a high price. There are countless neurons in your brain, and sometimes things get very bad. Even a seemingly gentle blow to the head will inspire you to speak a language fluently that you haven't spoken for decades. This is entirely possible, I can give two examples; There was once an 80-year-old man with a brain injury. As a result, the English he spoke for 70 years was almost erased, and he even talked about his Italian mother tongue when he was young.

Other diseases are more serious. Symptoms of brain diseases include inflammation, such as meningitis, or genetic failure, or physical diseases, such as schizophrenia. Dr Francisco Piruzzolo, a cerebrovascular expert at Baylor Medical College in Houston, said: "The brain is particularly complex, and our understanding of it is deepening, but there are still many problems that plague us. Once we don't handle it well, things often get very bad. "

Alzheimer's disease is also one of the most terrible brain diseases. About 4 million Americans suffer from this disease, of which about one in every 65,438+00 people is over 65, and about half of those over 85 are sick.

Simply put, Alzheimer's disease is caused by the killing of millions of brain cells. When this process goes through several months or years, patients obviously begin to lose their memory, gradually lose their language ability and logical thinking ability, and their body muscles can degenerate, eventually leading to death. This disease is likely to last for 3 15 years, and there are no cured cases so far.

Although Alzheimer's disease is the fourth biggest killer of human health at present, it still seems to be a mystery to us. People with this disease are in a variable state in the level of neuronal conduction required for communication between brain cells. High aluminum content in brain tissue is a common phenomenon, and researchers also study other factors, such as genes, brain injury, education level, gender and so on.

Unlike Alzheimer's disease, Parkinson's disease does not affect neurological function. But it can lead to serious physical problems, such as muscle trembling, slow movement and difficulty in walking. Parkinson's disease is caused by the lack of a conductive nerve cell called dopamine. Thankfully, at least 90% of patients will get better because of drug treatment.

Stroke is a fatal brain disease. The American Heart Association estimates that nearly 40% of stroke victims will die. This means that there are more than 57O00 people every year.

The doctor said: There are about two basic types of stroke. The first is caused by a blood clot in the artery from the chest to the brain. Blood clots block blood flow and prevent the delivery of oxygen and other nutrients, thus killing brain cells. Another type of stroke is caused by bleeding from a ruptured cerebral artery. This cuts off the blood flow to the brain, and brain cells die because they can't get fresh blood. Although the stroke caused by cerebral artery rupture and bleeding only accounts for about 1/5 of the total number of strokes, it is usually much more fatal than the stroke caused by thrombosis.

Creativity: the difference between humans and animals

This is the difference between Einstein and orangutans, Picasso and opossum, and you and cows. Because of the human brain, human beings are creative. Because the animal's brain can't stand upright and can't talk.

It is not only those who take off their thunder hats and write poems who have creativity and imagination. "Everyone has this ability," said William Shepard, project director of the Buffalo Creative Education Foundation in new york. In fact, creativity is increasingly becoming a skill needed for survival. You must keep up with the new era. Do things in a new way, otherwise, you and your company will fall behind. "

"Sure, just sit at your desk and say," Oh! My brain, be creative! Not enough. You must know how to put your mind into a creative state and learn how to use creativity to understand and accept new and unique information. "Shepard mentioned the following points:

Don't be too picky. A method called "speculation" can promote your creativity-whether alone or in a group. First determine the problem you want to solve, and then start thinking about the solution. They don't need to be clear, they don't need to be practical or even beautiful; You can keep coming up with ideas and then write them down immediately. Then don't try to judge whether these ideas are good or not. As long as you focus on the problem you want to solve, your thinking can be arbitrary.

After a while, maybe 10 minutes, maybe 5 minutes, stop recording. If possible, you can leave these things for a day or so, and then go back and have a closer look at what you have written. Chances are, your solution to the problem is in front of you.

Change the job at hand Sometimes we are so absorbed in the job at hand that our brain can't respond to stress. If you feel that you have hit a mental wall, you'd better take a break and do something completely different. If you can't seem to understand a paragraph-for example, you can pull the grass out of the factor. This gives your brain a chance to think carefully in a more relaxed state.

Have a dream date with yourself The next time your boss sees you daydreaming, tell him that you are actually doing something serious to improve your self-awareness and creativity. "daydreaming", thinking for a while, can let you avoid the immediate pressure for a while, and then continue to maintain the creative "magic" of your brain.

Daydreaming should actually be encouraged. "Shepard said," of course you shouldn't be absent from work for hours. But it will be very beneficial to take a moment to think about your own idea and imagine its application. "Moreover, it's best not to evaluate your ideas, let your ideas come and go at will, and consider them next time.

Making new connections Most of us think in a preset way: desks, chairs; Salt and pepper. If you want to exert your creativity, then you have to compare something that seems irrelevant at first glance, French steak: B-52 bomber. Then take a few minutes to list as many connections or similarities as possible. "This will help you to look at problems in a new way and from a new angle," Shepard said. "It can break the traditional way of thinking that we often fall into easily."

Once the preparations are done, get down to business. For example, if you think about the candy counter of the company another day, compare it with the Eiffel Tower, or compare it with the money supply in the conference room, and so on. Make a list, find out the relationship between them, and then see which one deserves further consideration.
