Article: The beater bar, the bottom part of the vacuum where dirt is sucked in, often accumulates dirt and hair. Use scissors to cut and remove any hair that is stuck in the bristles. This part in the process can be particularly unsanitary. Consider wearing disposable gloves. Apply rubbing alcohol to a cotton swab. Then rub the cotton swab over the beater bar to disinfect it. Rub the cotton swab over other parts of the vacuum that come into contact with the floor.  These areas are particularly susceptible to picking up dirt and disease because they are constantly coming into contact with dirtiest parts of your house.  Try to avoid spreading alcohol on rubber pieces of the vacuum. For most models, you will need to use your hands to spin the beater bar around so that you can disinfect all sides of it. Some models will allow you to detach the beater ball, which will make it easier to reach all sides. Read instructions to see if your beater ball can be removed. It will make the process easier.
Question: What is a summary of what this article is about?
Cut hair out of the beater bar. Disinfect the beater bar. Spin the beater bar and continue disinfecting.

Problem: Article: Purchase or borrow a camera that is good for use in landscape photography. The camera must have the capability for manual focus and remote shutter release. A digital display is also useful for lining up your shot and for correcting unforeseen image quality issues mid-shoot.  Digital single-lens reflex (DSLR) cameras are ideal for photographing lightning. Compact "point and shoot" cameras often respond too slowly and don't always have the required features. If you would like to use a compact camera, test it out first. While not necessary, a wide-angle zoom lens works best for lightning photography. The wide angle will allow you to fit more into the shot, maximizing your chances of catching an interesting lightning strike. Meanwhile, a zoom lense will give you the ability of adjusting the focal length to target a specific area. This option is especially useful in case the storm shifts position or you decide to focus on an interesting nearby object instead of the horizon. Not only is trying to take photographs in the middle of a storm dangerous, but it is also unlikely to produce quality photos. The optimal distance for lightning photographs is somewhere between roughly 6 and 10 miles from the storm. Any closer is too dangerous. Any further will likely give you small, blurry lightning strikes that look relatively unimpressive.  Figure out which direction the storm is moving. It's best to position yourself so that the storm moves across your field of view rather that towards or away from it. This will ensure that the storm will remain an optimal distance from you for as long as possible.  There are a few ways to determine a storm's direction. If the storm is moving fast enough, you can easily see its pattern of movement and use a compass. However, if you have access to the Internet, the most accurate way is to check your local meteorologist for details or use a storm tracking application.  Pick an interesting vantage point. The best lightning photographs are usually framed in such a way to include something else that's visually interesting, such as a city skyline or a natural monument. This gives the viewer a frame of reference for understanding the storm's large size. For lightning photographs, you will be using camera settings that cause the slightest movement to ruin an otherwise great shot. Don't try to hold your camera in your hands. You can use any object that keeps still to mount your camera. While a traditional tripod can work great, you can place your camera on something as simple as a bean bag chair for greater flexibility. No matter what you use for support, try to skew your camera's field of view up towards the sky. It is important to have a good view of the storm, but don't get too close. Successive lightning strikes often occur two to three miles apart, so keep in mind that you will need to stay a significantly larger distance away. Even so, lightning can also strike far from a storm's center and certain additional precautions should be taken:  Don't use an umbrella. When using a tripod, you should also use an extra long shutter release cable. A metal tripod can act as a lightning rod, and you want to be as far away from a potential lightning strike as possible. If possible, stay inside a building or a car with the windows rolled up. Stay at least 50 feet away from water and tall structures like trees and buildings.
Summary: Pick the right camera. Attach an optional specialty lens to your camera. Find a suitable location. Set up some type of camera support. Stay safe.

When you decide to try conceiving, it's important to be on folic acid. That means that if you go off your birth control, you need to start a supplement. Most women take a folic acid supplement in the form of a prenatal vitamin for the duration of the pregnancy.  You need 400 micrograms of folic acid daily. If you take a multivitamin, check what it has in it before adding a supplement.  You need to be prescribed an extra 4mg (far more than is found in over-the-counter supplements) if you have had a child with a neural tube defect. Talk to your doctor about additional folic acid if you (or your partner, or a relative) have celiac, sickle cell, or thalassaemia disease, or you are on anti-epileptic drugs. Choline can help reduce the chances of birth defects in your baby, so try to eat foods that are rich in it, such as egg yolks. Other good options include beef liver and cauliflower. Herbal teas and supplements may sound like a great idea; however, some can be harmful while you're pregnant or trying to get pregnant, such as St. John's Wort, ginseng, sassafras, and licorice. Ask your doctor about any supplement and tea you are taking. Though not definitive, it's possible that BPA can lower your fertility rates. Therefore, if you're trying to get pregnant, you should avoid this chemical. The best way to avoid it is to not consume foods out of hard plastics or cans labeled with number 3 or number 7.  Do not microwave in plastic containers. Heat can cause BPA to leach out into food. Purchase BPA-free plastic when available. Discard scratched or warped plastic ware, which are more likely to leach BPA. Choose frozen food over canned food when available. Can linings may be made with BPA. Heavy alcohol drinking is linked to lower fertility. In addition, if you consume alcohol while trying to get pregnant, you may be consuming alcohol after you get pregnant without realizing it, which is bad for the baby.
