Q: Your toes should be pointing upwards, towards the top of the water. Your knees should be at 90 degree angles. Your hips need to be at about 110 degrees. When your feet are flat against the wall, use them to push off. Your body should shoot off the wall like a torpedo. The harder you push off, the faster you will spring off the wall. As you are pushing off the wall, start rotating so that your back is facing the ceiling. Your belly will be facing down at the pool floor. Twist your hands and look towards the direction you want to twist. Don't move your head. After kicking off and during rotation, you can perform a few strong dolphin kicks. This is optional, and may be something you want to do after you get better. Swim around 10 to 15 feet ( approximately 5 meters) underwater using the butterfly kick in streamline position. Start the pull with the arm that was closest to the bottom as you rotated. Your hand should exit the water as you finish the pull. Now resume your freestyle stroke.
A: Untuck your legs and press your feet flat on the wall. Straighten your legs as your push yourself off the wall. Rotate onto your stomach. Resurface and begin swimming normally.

Article: Pericarditis occurs when the pericardium (a membrane around the heart) is swollen or irritated, usually from viral infection. The resulting chest pain usually feels like a sharp, stabbing pain in either the center or the left side of your chest. In some patients, though, the pain is more of a dull pressure that spreads to the jaw and/or left arm. This pain can worsen with breathing or movement. Some of the symptoms of pericarditis look a lot like those of a heart attack: Shortness of breath Heart palpitations Low-grade fever Fatigue or nausea Cough Swollen legs or abdomen Though pericarditis is often mild and resolves on its own, it's difficult to distinguish between its symptoms and those of a heart attack. It can also develop into more severe cases that can require surgery to relieve the symptoms. You need immediate supervision and diagnostic tests to find out what's actually causing the pain. Call emergency services or ask someone to take you to the nearest emergency room. Just like with heart attacks, early treatment is the best way to prevent the condition from worsening. The pericardium has two layers of tissue that rub together when inflamed, causing the chest pain. By sitting in this position, you can reduce the tissue friction and its resulting pain while waiting for medical attention. Taking a non-steroidal anti-inflammatory drug like aspirin or ibuprofen will reduce the tissue inflammation. This, in turn, reduces the friction between the two layers of the pericardium and eases your chest pain. Consult your doctor before taking these medications. With physician approval, take these medications three times a day with food. You should take a total of two to four grams of Aspirin per day or 1200 to 1800 mg of ibuprofen per day. Pericarditis is usually the result of a viral infection. You can treat it like the common cold to speed up your recover and eliminate the pain quickly. Rest and sleep will help your immune system function more efficiently, speeding up the healing process.
Question: What is a summary of what this article is about?
Learn the symptoms of pericarditis. Seek immediate medical attention. Ease the pain by sitting up and leaning forward. Take aspirin or ibuprofen. Get plenty of rest.

Problem: Article: The best way to store your Scoby is to make a new batch! Boil about 3.5 quarts (3.31 L) of water in a medium pot, add in around 8 black or green tea bags. Once the water boils, remove the pot from the heat source so it can cool. You can place your pot over ice to speed up the cooling process. If using loose-leaf tea, use about 2 tablespoons (29.57 g). Avoid using decaffeinated tea! As soon as you remove your tea from the stovetop, you can pour in your sugar. Mix it into your tea with a spoon until the sugar completely dissolves. Let your tea steep until the water has cooled, which make take 1-3 hours. Then, pour it into a large, clean glass jar. This is where you will house your Scoby as your kombucha brews. Wash your jar with soap and water before you pour in your tea. A 0.5USgal (1.9L) glass jar works great! Once your jar is filled with tea mixture, put your Scoby into your jar using your hands. It will likely settle at the bottom. Then, place a tightly-woven cloth on top of your opening, and screw on the lid tightly. Kombucha ferments the best at room temperature in a dark environment. You also want to keep it away from any potential damages, so situate your jar on a flat, stationary surface where it will not be bumped. You can place your jar in a cabinet, for example. Your Scoby will safely ferment at room temperature for 30 days, so you can let it brew without worrying.
Summary: Start a batch of kombucha to store your Scoby for less than 4 weeks. Add in 1 cup (200 g) of cane sugar and dissolve it into your tea. Pour your tea into a glass jar after it cools and cover it with a cloth. Put your Scoby inside the jar and secure the lid. Store your glass jar in a warm, dark spot.

Q: The three sisters need plenty of space to grow to their fullest potential. Ideally, the plot should be at least 10 by 10 feet (3.0m 3.0m) large. The plot should not be near any tree, sheds, walls, or other shaded areas. A neutral pH is ideal for growing corn, squash, and beans. Contact your local extension office or gardening store for a soil pH testing kit. If you need to, amend the soil before planting to get it to the right pH. If you need to raise the pH, mix lime into the soil. If you need to lower it, add sulfur. These can be bought at garden stores and nurseries. Heirloom varieties are more traditional, and they grow well together. Non-heirloom varieties of beans, in particular, may grow too large and overwhelm the other plants if used. Choose flint, dent, or flour corn varieties. While you can plant sweet corn, you will have to harvest it much earlier than the other plants. Choose pole or runner beans instead of bush beans. Dry beans, such as pinto or kidney beans, or green beans work well. Pumpkin or squash works well in this configuration. Winter squash and sugar pumpkins are ideal. Use your hands to push and pack dirt into mounds. Flatten out the top of each mound. Each mound should be 1 foot (0.30m) high and 34 feet (0.911.22m) wide. Keep each mound 34 feet (0.911.22m) apart. Mark the center of each mound with a stick. This will help you measure and find your mounds. When you plant the vegetables, corn will grow in the mound with beans around the corn and squash around the beans. Many people plant the three sisters because they grow well organically. To keep up with this practice, prepare the soil by applying an organic high-nitrogen fertilizer around the mound. You can use manure, fish emulsion, orfor a very traditional approachfish scraps. If you decide that you don't want an organic garden, you can use a basic 10-10-10 fertilizer.
A:
Choose a large spot that receives at least 6 hours of full sunlight. Test the soil for a pH between 5.5 and 7. Select heirloom varieties of corn, beans, and squash. Create mounds for each plot of plants. Fertilize the soil with traditional or organic fertilizers.
