Article: Danios enjoy a variety of food sources. Commercial produced flakes will usually suffice. You can also feed them blood worms, daphnia, and brine shrimp. Danios are hearty and are comfortable in temperatures from 65 to 75 Fahrenheit. You can often maintain this temperature without a heater, but a heater will help. A slightly higher temperature, 78 Fahrenheit, is optimal for encouraging breeding. When you clean the tank, you do not need to remove all of the gravel, however, you should use a siphon to suck up the waste that accumulates on the bottom of the tank. Use a scrapper to remove algae from the glass on the tank. After finishing these tasks, remove and replace 10-15% of the water.  Do not remove fish when changing the water, this will cause unnecessary stress. When replacing the water, put new water into a bucket that is exclusively used for this purpose (If you use it for household tasks it might accumulate dangerous chemicals). Test and treat the water as discussed previously. Use a siphon to slowly introduce the new water back into the tank.
Question: What is a summary of what this article is about?
Feed the danio. Maintain tank temperature. Clean the tank weekly.

Problem: Article: How the herbs taste will depend on when you cut them from the plant. You will get the best flavor while the herbs are still tender, which you can feel with your fingers. If the herb is flowering, this will be just before the buds open.  You can still dry herbs that have flowered, but the taste will be bitter.  This process works for all herbs. If your herbs have already flowered, you can deadhead the flowers. This will allow more leaves to grow, which you can harvest and dry. A sunny day is the best time to cut your crop because the herbs will be dryer. The more moisture that remains on the herbs, the harder it is to dry them. It’s best to wait until mid-morning, as the dew should be gone by then. You can use regular sharp scissors or small pruning shears. Place the cut herbs into a jar of fresh water until you’ve completed the harvest. Leave at least 4 to 6 inches (10 to 15 cm) of stem for the plant’s regrowth. This includes herbs like sage, basil or mint. If it’s easy to hold just the leaf, then it’s best to remove them from the stalk before drying. You can also cut the leaves from the stalk with your sharp scissors, but this will be more time consuming. This includes herbs like fennel, dill, and rosemary. While these herbs will eventually be removed from their stalks in most cases, its best to wait until after they are dry as the stalks make them easier to handle. Additionally, some dishes may look better with these herbs still on the stalk. It’s easy to mix herbs together or ruin the flavors of the herbs by drying them together. To protect the flavor, only dry one herb at a time.
Summary: Harvest your herbs when they are tender just before flowers form. Choose a warm, dry morning after dew has evaporated. Use scissors to cut the stems just above a leaf or leaves. Pull large-leaf herbs from their stalks before drying. Leave small-leaf and feathery herbs on their stalks until after they dry. Limit your harvest to one herb at a time.

INPUT ARTICLE: Article: Keep your elbow at your side. Your fingers should be pointing at an angle, outwards and towards the opposite hand's direction. Take your dominant hand and place the palm on the palm of your non-dominant hand. You want the thumb of your non-dominant hand to line up with second finger joints of your dominant hand. The edge of your dominant hand's palm should stick out a little. Both your hands' fingers should wrap firmly around your hands. Right now your hands are perpendicular with each other. You need to rotate your dominant hand upwards slightly. Move your palms in and out so that the space between them opens and closes. You'll need to practice this and fine tune the movement and speed to get the best realistic fart noise.

SUMMARY: Lay your non-dominant hand flat with your palm facing upwards. Put your dominant hand on your other hand. Wrap your fingers around your hands. Rotate your hands slightly. Smash your palms together.

An endoscopy can serve several purposes. Your doctor might advise an endoscopy to investigate symptoms such as nausea or vomiting. If your doctor recommends an endoscopy, take time to learn why.  In addition to investigating digestive symptoms, your doctor might use the endoscopy to collect tissue samples. This is also known as a biopsy. Tissue samples can help your doctor to diagnose your condition. The tissue samples can be tested for diseases such as anemia and certain cancers. If your doctor suggests this procedure, you do not need to immediately be alarmed. It is a common procedure and used to diagnose many conditions. Talk to your doctor about what the procedure entails. You can also ask him to provide additional resources, such as pamphlets or useful web sites. If you know what to expect, you will feel more comfortable about having the procedure.  You will be awake during an endoscopy, however you will also be slightly sedated with a rapid onset and short duration medication. It is a same day procedure that takes place in a doctor's office or exam room. During the procedure, you will lie down either on your back or side. Your doctor may give you a sedative to help you relax. The endoscope, which includes a small camera, will be inserted into your mouth. Your doctor will extend the scope down into your esophagus so that the camera can capture images. Your doctor might use other small tools to gather the tissue samples. You will not be able to talk during the procedure, but you will be able to breathe and make sounds. It is important to understand that there are actually two common types of endoscopy. One is the upper endoscopy and the other is a colonoscopy. Make sure to clarify with your doctor which type of procedure you need.  Your doctor will use an endoscopy to view the upper digestive tract, or a colonoscopy to view the lower digestive tract. The upper endoscopy is the procedure where the scope is inserted through the mouth. It will allow your doctor to look at the small intestines and stomach in addition to the esophagus. During a colonoscopy, the camera is attached to a flexible tube inserted through the rectum. This procedure allows your doctor to examine the large intestine, colon, and rectum. Both procedures are used to diagnose disease and investigate symptoms. Both are common, same day procedures. You may be disconcerted if your doctor recommends an endoscopy. It is normal to be nervous about undergoing a new procedure. Take time to ask your doctor several questions about his recommendation.  Gain an understanding of why you need the procedure. Try saying, "What, specifically, makes you think this procedure is necessary for me?" You can also ask about the procedure itself. You might say, "Can you tell me if it will hurt?" Ask your doctor about possible side effects. You can also ask how regularly he performs the procedure. Feel free to take notes. You might hear some unfamiliar medical terms and want to write down what they mean.
