article: Use the socket on your skateboard tool to remove the nut on the end of the axle. If you don't have a skateboard tool, or it doesn't have a socket, use a crescent or socket wrench. Wheel nuts are usually ½” (13 mm), so use that size.  Take the nuts off of all four wheels at once if you are changing all of the bearings. Set the nuts somewhere that you won’t lose them. If you know for sure which wheel is the problem, only remove the nut and bearings from that wheel. You will use the axle itself to pry the bearings out of the wheel, so don’t slide the wheel all the way off of the axle. Move the wheel toward the end of the axle so that only the bearing is still on the axle.  If your skateboard tool has a bearing puller on it, feel free to use that to remove the bearings rather than the axle. If you want to use the bearing puller, take the wheel completely off of the axle. Be sure not to lose any washers that are between the wheel and the axle. When the axle rod tip is just inside the bearing, use leverage to pry the wheel away from the skateboard truck. Place the heel of your hand on the bottom edge of the outside of the wheel. Place your fingers on top of the wheel and use leverage to pry the bearing out of the wheel.  Think of the motion you’d use to open the tab on a pop can or pry a bottle cap from a glass bottle. If you are putting new bearings in the wheels, then it doesn’t matter if you break the current ones. If you are going to clean the bearings and put them back in, be gentle when you are prying them out of the wheels. If you are using a bearing puller, insert the tip into the bearing so it hooks the bearing’s edge and simply pull the bearing out of the wheel. Flip the wheel over and insert the tip of the axle rod into the second bearing. Repeat the prying process to remove the second bearing from the wheel. Set the bearings aside to be cleaned, or throw them away if you are putting new bearings in the wheels.

article: At-home sperm tests have been found to be accurate around 95% of the time. Masturbate into the cup the kit provides for you and complete the test exactly as indicated in the instructions. Read the instructions carefully beforehand so you know what to do and what not to do.  Generally, you will collect your sample in a cup, transfer the sample to the testing kit after a specific amount of time, and read the results.You may also have to add another solution to the sample, but this depends on the test. Tests like these are available at many drug stores and pharmacies. Results should be available in about 10 minutes, though this varies by test. A normal sperm concentration is considered to be above 20 million per milliliter. If your results are lower than that, consult your doctor for a complete infertility workup. Some tests simply tell you whether your count is normal or low. Others may be more exact. This varies by test, so read the instructions carefully. At-home tests do not measure other factors that affect fertility. If you are having trouble conceiving, consider seeing a fertility specialist even if your at-home test shows normal results. At-home tests do not check:  How much semen you ejaculate at one time (semen volume) The percent of your sperm that are alive (vitality) How well your sperm move (motility) The shape of your sperm (morphology)

article:
The big four gluten culprits are wheat, rye, barley, and triticale. Avoid these in all cases, whether you are only gluten-intolerant or have celiac.  Wheat to avoid includes kamut and spelt. Because wheat often goes by another name, here are varieties of wheat to also definitely avoid:  Bulgur Durum flour Farina Graham flour Kamut Semolina   Rye contains a protein called secalin, which is a form of gluten.  Triticale, a cross between rye and wheat, is actually a hybrid designed in laboratories in the late 19th century.  Barley is the last big gluten cereal to avoid. It is commonly made into meals and used in alcohol production, among others. White oats themselves do not contain gluten, they are often cross-contaminated with wheat because both are commonly processed in the same facilities. Avoid eating oats and oatmeal unless the packaging specifically designates the product as gluten-free. In theory, the distillation process removes all gluten proteins if done properly, even if the alcohol was manufactured using a glutinous grain (such as wheat, barley, or rye).  You can safely drink alcohols such as vodka manufactured from wheat, but be wary of beer. Look for beer that is specifically designated gluten-free. In theory, the distillation process removes all glutinous proteins. But in reality, cross-contamination may occur. Not only this, but some distillers may add mash to alcohols after distillation as a filler. This may cast doubt on alcohol's ability to deliver truly safe results. If you really want to be careful, stick with potato-based vodkas, tequilas and mescals, or rums. These all contain non-gluten grain sources, so they should be fine to drink. Checking labels is important. While many of the following kinds of foods have been and are being made gluten-free, many of them aren't. It's better to be safe than sorry. Avoid:  Breads, croutons, cereals, and crackers Cookies, cakes, and candies Imitation meat, imitation seafood, processed lunch meats, and "self-basting" poultry Salad dressings, gravies, sauces (such as soy sauce), and vegetables in sauces Pastas and "seasoned" rice mixes Soups, matzo, and processed snacks like chips (potato chips and tortilla chips)
