INPUT ARTICLE: Article: The most common way to get a crooked (dislocated or subluxed, meaning partially dislocated) shoulder is from a sports injury, a fall, or another accident. There is usually one precipitating event, and most people feel a significant amount of pain around the shoulder area at the time of their injury.  Shoulder dislocations (partial or complete) are quite common, as the shoulder is a very mobile joint. It is essentially a "ball-and-socket" joint, where the top of the arm bone (the "ball") fits into the shoulder (the "socket"). Because the shoulder facilitates such a great range of motion for the arm, the joint is looser than most other joints in the body, making you more prone to dislocation or subluxation. Examples of ways you can dislocate your shoulder are falling on an outstretched hand, falling on the shoulder itself, a forceful blow from the front pushing your shoulder backwards, or a vigorous twisting of the upper arm. You should also avoid carrying a heavy bag (like a backpack, purse, diaper bag, or messenger bag) on one side of the body. Consider lightening your load or carrying things in a backpack — with both straps on and properly adjusted. In other words, if you have already dislocated your shoulder (i.e. had a crooked shoulder) once or more in your life, the probability of it occurring again is significantly higher. Common symptoms include:  Pain Swelling and/or bruising around the shoulder area Difficulty (and likely pain) when attempting to move your arm Deformity of the shoulder Possible numbness, tingling, or weakness in your arm or hand (if you have this, it warrants immediate medical attention and a prompt visit to the emergency room). If you suspect you may have a shoulder dislocation, it is best to see a doctor to have your shoulder re-aligned. If you are on a sports team with trained personnel such as physiotherapists who are comfortable re-aligning your shoulder, you can let them give it a try. However, it is a risky procedure if done by someone who is inexperienced, so your best bet is to go to your local emergency room for help from a doctor. If your shoulder is not dislocated but your it still looks crooked, or one shoulder is higher than the other, you may have overactive muscles in the upper neck area on one side. Talk to your doctor about stretches and exercises to release the muscle. This may be caused by cold drafts, posture with shoulders hunched up, sitting a computer, a seat that is too high, or muscle knots and trigger points.

SUMMARY: Know the common mechanisms of shoulder injuries. Understand that repeat injuries are very common. Recognize the symptoms of a shoulder dislocation. See a doctor for definitive diagnosis and treatment.

In one sentence, describe what the following article is about: Let's say you're solving for x in the following problem: √(2x+9) - 5 = 0 You have to move the part of the equation with the square root sign to one side of the equation before you can proceed. So, you'll have to add 5 to both sides of the equation. Here's how:  √(2x+9) - 5 + 5 = 0 + 5 √(2x+9) = 5 Just as you would divide both sides of an equation by a coefficient that is being multiplied by x, you would square both sides of an equation if x appears under the square root, or the radical sign. This will remove the radical sign from the equation. Here's how you do it:  (√(2x+9))2 = 52  2x + 9 = 25 Combine like terms by subtracting both sides by 9 so that all of the constant terms are on the right side of the equation while x remains on the left side. Here's what you do:  2x + 9 - 9 = 25 - 9 2x = 16 The last thing you have to do to solve for x is to isolate the variable by dividing both sides of the equation by 2, the coefficient of the x term. 2x/2 = x and 16/2 = 8, so you're left with x = 8. Plug 8 back in to the equation for x to see if you get the right answer:  √(2x+9) - 5 = 0 √(2(8)+9) - 5 = 0 √(16+9) - 5 = 0 √(25) - 5 = 0 5 - 5 = 0
Summary: Write down the problem. Isolate the square root. Square both sides. Combine like terms. Isolate the variable. Check your work.

INPUT ARTICLE: Article: If you typically use a purse with no closing mechanism, get a purse with a twisting latch or zipper. These purses are harder to open and a pickpocket likely won’t bother trying to slip their hand inside. If possible, use a purse with a lock on it to ensure that nothing goes missing while you’re traveling. The smaller you can make your purse, the better. Big purses provide more space for a thief to operate. To avoid having your bag ripped away from you, keep your bag or backpack as close as you can to your body. Pull the straps on your purse or backpack to shorten them and keep the bag closer to your body. This will make it much harder for someone to reach into your bag while you’re traveling. If you really want to avoid giving pickpockets a chance at your bag, you can walk around with it hanging on your chest instead of your back. If you take a seat at a restaurant or sit down on the bus, rotate your bag around your shoulder and hold it on your lap. If you set it down on the floor or hang it off the back of a chair, it’ll be an easy target for thieves. You’re also more likely to forget about your bag when you get out of your seat if you set it down. A purse strap can be cut, making it easy to rip the bag away from you in a matter of seconds. However, a nylon fanny pack that sits tightly around your waist is much harder to cut or remove. Take your purse and move the cards and cash to your fanny pack. Tighten the straps around your waist and rotate the bag so that the pouch sits just below your belly button. This will make it easier to keep an eye on your valuables. Do not use a fanny pack with the standard plastic buckle. Instead, get an anti-theft fanny pack online. These packs have tougher buckles, and can often be locked to prevent thieves from accessing their contents.

SUMMARY:
Choose a purse with a complex latch to deter pickpockets. Shorten the straps on your bag or purse to keep it close to you. Hold your bag or backpack instead of setting it down when you sit. Transfer the contents of your purse to a fanny pack.
