Article: Angina is chest pain that can feel like a slight pressure, a burning, or a fullness. It is often mistaken for heartburn. Angina can be a sign of coronary heart disease, which is the most common cause of heart attacks. If you feel any type of pain in your chest, it's best to get it checked out right away.  Most angina pain occurs in the chest. However, it may also occur in the arms, shoulders, neck, jaw, throat, or back. It may be hard to tell exactly where you're feeling the pain.  Angina pain usually gets better once you've rested for a few minutes. If your chest pain lasts for more than a few minutes or doesn't improve with rest or angina medication, seek emergency medical assistance.  Some people experience angina after exercising, and it's not always a sign of disease or a heart attack. A change in normal patterns is the most important thing to watch for. If you have what you believe to be painful indigestion, you may actually be experiencing angina. Make an appointment with your doctor to determine the cause of the pain. Arrhythmias are abnormal heart rhythms, and they're present in at least 90% of people who have heart attacks. If you have a fluttering feeling in your chest or feel like your heart “skipped a beat,” you may have an arrhythmia. See a specialist who can conduct testing to determine the cause of your symptoms.  Arrhythmia may also display more serious symptoms, such as dizziness, lightheadedness, fainting, rapid or pounding heartbeat, shortness of breath, and chest pain. If you experience any of these symptoms with arrhythmia, seek emergency medical assistance.  Although arrhythmia is very common, especially in older adults, it can be a sign of severe medical issues. Do not simply ignore an arrhythmia. Consult with your physician to be sure you do not have a more serious condition. In older people, these symptoms may actually be a sign of heart problems. Seek medical attention if you experience unexplainable cognitive difficulties. Women are more likely than men to experience unusual, sudden, or unexplained fatigue as a symptom of heart attack. This fatigue may start a few days in advance of an actual heart attack. If you experience abrupt, unusual fatigue without having changed your daily activities, talk with your doctor immediately.

Seek medical attention for angina. Determine whether you have an arrhythmia. Be aware of disorientation, confusion, and stroke-like symptoms. Look for unusual fatigue.
Article: If you're keeping your food diary as a way to track calories and get in shape, it makes sense to write down your physical activity, too.   Record the type of activity and time spent doing it.  If you can, also add about how many calories you've burned during that particular exercise. See how your level of exercise affects your hunger level and what you eat.  Make notes whether you've noticed increased hunger overall or if you experience increased hunger immediately after a workout. If you're keeping a food diary to make sure you're getting enough of a certain nutrient, you might want to record the nutrition information for each item. It's easy to find nutrition information for any type of food online and many food journal apps automatically provide this for you.  Examples of nutrients to track include:  Fiber Protein Carbohydrates Iron Vitamin D A food diary can be a motivating tool when you have a goal you want to reach that's related to your diet. Whether you want to lose weight or you're just trying to eat more fruit and vegetables, tracking your progress will inspire you to keep going and show you where there's still room for improvement. Here are a few ways you can track it:  Record your weight. Write it down at the end of each week so you can see how it has fluctuated. Note important milestones. If you successfully eliminated gluten from your diet for a month, note it in your diary. Record how much exercise you can perform. For example, record your progress toward running a 5k. Since you're already writing down everything you eat, why not also write down how much it costs? It's a great way to stay within your food budget for each day, week, and month. You might be surprised when you find out where you tend to spend the most money.  Note how much you spent on each meal. Include meals you make at home as well as the meals you eat out. Look for patterns to determine how much you spend on food each week or month, and find places where you can cut back. It might be helpful to tally up how much you spend on food purchased outside of the home.  For example, you might spend money on an afternoon coffee or lunch out with coworkers.  Over time, these little expenses can add up.

Record physical activity. Record nutritional information. Track your progress toward a goal. Track food expenses.
Article: Major scales figure prominently in flamenco music. If you've already been playing guitar for a while, they are likely some of the first scales you learned as well. Try playing the scales in a way that emulates the basic rhythm and meter of common flamenco styles.  For example, the flamenco style Alegrías is typically in C Major. Since this is a fairly simple scale with no sharps or flats, it can be a good place to start. Practice switching between different scales. This will give you the ability to switch keys while you play, a technique known as modulation. This technique figures prominently in pieces performed by many famous flamenco guitarists. Barre chords require significant finger strength, but they are essential to master if you want to play flamenco guitar. Barre chords allow you to play more chords up and down the fretboard, and to transition between those chords more quickly.  To make a barre chord, you place your index finger over the fretboard so that you're pressing down all of the strings at the same time. If you're just starting out, placing your middle finger over the top of your index finger can help you understand the pressure required to press down the strings cleanly. Press your thumb into the back of the neck of the guitar and apply even pressure to stabilize your hand. For example, you can make an E Major barre chord by barring the 8th fret with your index finger. Place your ring finger on the 10th fret of the 5th string, and your pinky finger on the 10th fret of the 4th string. Then place your middle finger on the 9th fret of the 3rd string. Strum and adjust your fingers until you have a clean sound. You know how to make chord shapes with your left hand, but you're probably used to just strumming the chord altogether. With an arpeggio, you play each of the notes of the chord individually.  You can practice different playing techniques using an arpeggio before you advance to learning flamenco melodies. Arpeggios can also be a good way to stretch and warm up your fingers. For the picado technique, you'll strike the strings of your guitar by alternating your index and middle fingers. If you already know single-line scales, you can use them to practice this flamenco technique.  For the picado technique, strike the string downward, rather than plucking the string up as you would in classical guitar. This difference can take some getting used to, especially if you have a lot of experience with classical guitar, so be patient. Even though you're supposed to play picado very fast, start out by playing slowly until your fingers are used to striking the strings correctly.
Question: What is a summary of what this article is about?
Focus on Major scales. Practice basic barre chords. Play your chords as arpeggios. Use the picado technique to play scales.
