Q: Heart palpitations, chest pains, and severe abdominal pain are all signs of a serious allergic reaction. If you're experiencing any of these symptoms, stay calm. You may be experiencing a reaction that could be anaphylaxis. Get immediate treatment to avoid life-threatening symptoms such as anaphylactic shock or a heart attack. Focus on your breathing to help calm yourself down and make sure you're getting enough oxygen. If you think you may be having a heart attack, call emergency medical services immediately. Some discomfort, nausea, or even diarrhea after you eat something could just be a harmless effect of eating food that was maybe too spicy, greasy, or heavy. However, if you experience extreme nausea, vomiting, or diarrhea that won't go away after a few hours, you may be having a serious gastrointestinal reaction that needs to be checked out by a doctor to make sure it's not dangerous. Nausea, vomiting, or diarrhea could be a sign of a more serious systemic allergic reaction. Call your doctor if you're still experiencing serious symptoms 3 hours after you eat. They may ask you to seek emergency treatment. A serious allergic reaction can cause a major drop in blood pressure, which can cause you to feel disoriented or extremely anxious. If you suddenly find yourself lost and confused, or your heart is beating fast and you have anxiety, you may be experiencing the onset of a serious reaction. Pay attention for any other potential symptoms that could confirm that you need immediate medical attention. Sometimes a serious reaction caused by a food allergy can take time to affect your whole system, and your blood pressure may be affected first, which could cause you to feel anxious and confused, but otherwise normal. Keep an eye out for additional symptoms.
A: Check for pain or tightness in your chest or abdomen. Pay attention to nausea, vomiting, or diarrhea after you eat. Take note if you suddenly feel confused or anxious after eating.

Article: The whole point of a verbal bully's attacks is to unsettle you, so don't give them the satisfaction. Stay calm, cool and collected despite any taunts or insults. To do this, it may help to breathe deeply, count silently, or mentally repeat an affirmation, such as "I will remain calm." Ignoring the person is an option. An even more powerful response, however, is to make it clear to the person that the remark doesn't bother you. Make eye contact with the person, then shake your head in dismissal and look away. Most verbal bullying is carried out because the person hopes to offend you. If you can see any truth to their comment, throw the attacker off balance by agreeing with them. When you accept the statement, it loses its power and the attacker loses relevance. For example, someone says "You're fat," you might say "You're right. I am fat." Avoid becoming defensive with the person. Instead, put the attacker in the hot seat by pulling apart their remark. Analyze the remark and ask questions about it. For example, someone says, "You're stupid." You might respond with "Wow, stupid is such a strong word. Is there a reason you're trying to insult me?" However, if the bullying behavior is out of control or you feel unsafe, do not have any contact with the attacker. Just walk away. If you witness someone else being verbally attacked, help defend them by bringing the attacker's common decency into question. In response to their "bad parent" role, play the role of the overly kind parent. For instance, if the attacker calls your friend a name, you might say, "Carl, name-calling doesn't look good on you. Show everyone that there's a decent human being under there somewhere." They'll likely feel shamed by their behavior and apologize.
Question: What is a summary of what this article is about?
Remain calm. Dismiss the person's attack. Agree with them, if it's true. Dismantle the attack. Play the kind parent.

Q: The focal length is represented by two numbers with a dash in between (i.e., 18-55). It marks the distance from the camera lens to the sensor. A wider range makes a camera better at taking photos from a distance. A shorter range means a camera will be better at shooting single scenes up close. For example, if you take a lot of photos of family events, you're taking mostly close-up shots of one scene. If choosing between a focal length of 18-55 and 18-35, go for the 18-35 lens. Image stabilization prevents blur by keeping the camera steady when taking photos. Pentax and Olympic cameras have photo stabilization built in with a camera's body, so you won't need a lens with this feature. If you have another brand of camera, however, look for a lens with image stabilization. Image stabilization is labeled differently between types of cameras. Canon simply uses Image Stabilization, or IS. Fujifilm, Panasonic, and Samsung us the term Optical Image Stabilization (OIS). Nikon uses Vibration Reduction (VR). Sony uses Optical Steady Shot (OSS). Sigma uses Optical Stabilization (OS). Tamron uses Vibration Control (VC). Aperture refers to the amount of light a camera lens allows in and is represented by f-stop ratings (i.e., F4). Smaller numbers indicate a camera lets in more light. A smaller aperture works great for more creative photography, as they allow you to focus in on a close up of one specific object. However, a larger aperture works best if you're just photographing to capture events in your daily life. A larger aperture allows you to take photos indoors without flash and shoot without a lot of light. For example, if you use your camera to photograph family get togethers, an f-stop rating of F4 should be fine. However, if you use your camera to take creative photos for a photography class, go for a lower f-stop rating, such as F2. A prime lens is generally a solid choice, as it can be customized for a variety of photo types and is generally the most versatile. However, if you're taking very specific types of photos, pick a lens type that will provide the right zoom for your needs. Wide-angled lenses allow you to better photograph interiors of buildings and other structures. Macro lenses work great for extreme closeups, such as nature shots of leaves and flowers. Telephoto lenses can be helpful for long distance shots.
A:
Pick a focal length designed for the type of pictures you take. Check if you need image stabilization. Use the f-stop rating to select your aperture. Check how the lens type affects zoom capabilities.
