Article: Chronic bronchitis affects over 10 million people in the US and is responsible for 40,000 deaths. It is condition that lasts at least three months and occurs at least two years in a row. It is caused by inflammation that is accompanied by swelling and excessive mucus production. This causes the lungs to lose their cilia, which are the hair-like appendages that help move mucus and other substances through the respiratory system. When this happens, the mucus stays stationary, which causes the growth of bacteria and stops up the airways. The primary cause of chronic bronchitis is tobacco use. Because of this, chronic bronchitis is a common precursor to chronic obstructive pulmonary disease (COPD) and emphysema. The people at the most risk of chronic bronchitis are those who are or have been heavy smokers. You are also at risk if you have had severe bacterial or viral infections that affected the lungs or if you breathed in industrial dusts and fumes. When tobacco smoke or air pollutants such as dust or soot is breathed into the airways, it causes them to become irritated. The cells of the lower respiratory tract that secrete mucus, the goblet cells, go into overdrive. This causes them to secrete mucus at a very high rate into the respiratory passages, which causes a chronic cough. Research indicates that inflammation of the airways persists for more than 13 years after a person has stopped smoking. People with occupations such as metal molders, grain handlers, and coal miners are at an increased risk due to the excessive environmental irritants. The main symptom of chronic bronchitis is sputum production from a cough that occurs every day for at least three months, which reoccurs at least two years in a row. The mucus causes obstructions to airways, and this causes even thicker mucus as a consequence. Unlike acute bronchitis which starts within in a few days, chronic bronchitis's onset is gradual. The mucus produced is typically yellow or brownish in color. You will likely also have chest tightness, shortness of breath, and sometimes struggling to breathe. You may also experience fatigue, a sore throat, muscle aches, nasal congestion, and headaches. Since chronic bronchitis often comes hand in hand with COPD, you may see all the symptoms of COPD such as wheezing lungs, weight loss, and cyanosis, which is a bluish or grayish skin discoloration due to low oxygenation. Your doctor will likely give you a chest X-ray to check the extent of the damage. This will also exclude pneumonia or lung cancer. Chronic bronchitis will not show any specific signs on the X-ray, but it will tell the doctor if your condition has evolved into COPD. You may also get a pulmonary function tests. These will test your lung capacity and oxygen levels. These are also likely given while you are receiving treatment over a period of time to see if the treatments are working. The major point of treatment is to quit smoking immediately. This can be done with or without help. If you have smoked for a long time, you may find it easier with help, such as nicotine patches and gums, group therapy, prescription medication, and shots. If you have already quit smoking, there are different kinds of treatment, depending on how bad your chronic bronchitis is. People with chronic bronchitis should get a yearly flu shot as well as a pneumonia shot. For chronic bronchitis caused by any factor, you may be given special breathing exercises to increase your lung capacity and help your respiratory system. You may also be told to do more modest exercise, such as light walking or other light cardiovascular exercises. This should be done for 15 minutes at least three times a week to start. Your doctor may also prescribe medication for the condition, such as inhaled beta agonists and steroids to help open up your airways. This works for any cause of bronchitis. You may also be prescribed oral steroids, but talk with your doctor first about the side effects. Antibiotics are sometimes prescribed when you have an acute flare caused by a bacterial infection. If you have extremely low oxygen levels, you may be given supplemental oxygen. This is typical in cases that have progressed to COPD.

Put your body between passes that you receive and any defenders around you. Turn your hip or you back to the defense and try as much as you can to shield the ball from them. Messi will often already have his eyes up and looking over his shoulder at an opponent as soon as he traps the ball. When you trap a pass, try to do it by controlling it with the foot farthest away from the opponent. Though Messi often gets close enough to touch the defense, he's always got the ball closer to him and his center of gravity than his opponents. To start off on the right foot (ha!), accept the pass and trap it to create space in which to work. Keeping your eyes up, decide which direction is more likely to allow you enough space to maneuver around the defender. His hips won't lie: Look closely at the defender's hips to see which direction they're turned and what he seems to be anticipating you'll do. If you're right-footed, most defenders will instinctively guess that you'll go right, which might be your natural tendency anyway. Use that misconception to your advantage. Control the ball with the foot that matches the direction you're eventually going to go and take a step with the other foot. Messi's signature move happens so quick it's easy to miss, which is why it's so effective against defenders. Basically, to juke out a defender, Messi takes one stutter-step in the fake direction, feints, and then dribbles in the opposite with the outside of his foot. Messi brings the defender in and forces him to reveal his hand and make a mistake before blowing past them finding space. Messi isn't a flashy dribbler like Ronaldhino or a master of the step-over like Cristiano Ronaldo, he just uses simple changes of direction and ball control to do inhuman looking things. Drop it into high gear when you decide to switch direction. Blow past your opponent by flicking the ball in the direction you want to go and moving into your quick-dribble that you've been practicing so aggressively. You don't have to go super-fast to find space, you just need to make the smart dribble and catch the defender flat-footed and out of position. He won't be able to touch you.
