Appropriate training is playing a musical instrument, crossword puzzles, learning a foreign language, and even computer games. After all, according to new data, hour of play on a computer for 40 weeks "rejuvenates" the brain for 10 years. In addition, it is necessary to dispel another "myth"- brain size have nothing to do with the mental faculties of man striking example of this is Einstein, whose brainsize does not go beyond the average..
Myth 2: the slower the metabolism, the thicker the person
We all have heard that thin people supposedly won in the "biological" lottery, because they can eat anything you want without fear of stout.However, studies of thin and fat people show that people who have weight problems, often the metabolism is faster than in lean.The thing is that obese people tend to have sedentary lifestyles.At the same time, the fight against excess weight fairly easily.Even just getting up from behind his desk at work can increase metabolism by 40%.
Men can drink more alcohol than women
It's true.Biologically, men are more adapted to the consumption of alcohol.Not only that men larger, and that they have an additional stomach enzyme that detecting alcohol immediately starts its process.Therefore, only half of the alcohol, which is able to drink man, enters the bloodstream.Women, on the contrary, such an enzyme in the small blood gets more alcohol and they get drunk faster.

Myth 4: there is nothing that is as old as the sun
customary to think that the sun - the main culprit of the appearance of early wrinkles, but all the research shows that the main cause of aging - it is stress.It was he who promotes aging of the arteries, heart disease, stroke, memory loss, weakening of the immune system and cancer.However, not all stress is really harmful to the body.The most dangerous so-called outstanding, "hanging" issues that people are constantly postponed.The stress of a particular event, such as a puncture on the road is not so dangerous as stress from similar problems plaguing.However, the stress of major events such as the loss of a loved one or the work will have a significant effect of aging.However, there is good news: they consist in the fact that there are very simple ways to neutralize the stress.Good help exercises, deep breathing, as well as laughter.From aging perfectly helps with my friends.

Myth 6: cholesterol - the main cause of heart disease
This common statement is absolutely incorrect.The level of cholesterol in the blood is important, but based on it is impossible to tell whether a person has a heart attack.In this sense, the superiority belongs hypertension.Under arterial blood pressure in the arteries of the holes can be formed.The body eliminates these lesions with the help of cholesterol.If cholesterol is useful, the holes clogged smoothly.However, if the cholesterol is harmful, then the vessel wall forms a semblance of cover, which eventually occludes the vessel.This leads to a heart attack.The optimal pressure is 115 to 75, and if it is above 140 over 90, then you are already at risk.
Myth 7: You can breathe properly
turns, deep breathing can be more effective than do most people.Less than ten per cent of people are aware of what it means to take a deep breath, because from childhood we are taught that this works only one chest.However, it is not.The main thing with a deep breath - is to involve the stomach.We need to take a breath and push out the stomach.As a result, the diaphragm will go down, and the light goes down air penetrates deep into the lungs.As you exhale, you need, on the contrary, involve the stomach.Aperture will go up, pushing air out of the lungs.Reported NEWSru.com.
