Article: If you use your Oculus Rift regularly, it’s a good idea to clean it on a monthly basis even if it doesn’t look dirty. Dust, grease, and skin dander may not always be visible when they accumulate on your gear. If any part of your headset seems dirty between monthly cleanings, go ahead and clean it as soon as you notice it’s dirty. To reduce the amount of oils, grease, and dead skin that ends up on your headset, it’s a good idea to clean your face before you put the headset on. Remove any makeup and wash your face thoroughly with soap and water or a skin-safe anti-bacterial wipe. When you wear your headset, sweat and oil tend to accumulate on your face cushion and headphones. You can help reduce this by keeping your face as cool and dry as possible while you play. Keep the air conditioning on or position a fan to blow towards you while you are wearing the headset. Leaving your headset out can cause it to accumulate dust, even if you use it often. A box, drawer, drawstring bag, or even backpack can be a good way to keep your headset clear of dust. Some players experience foggy lenses when the hot air exhaled through their nose gets into their headset. You can help reduce this effect by placing a thin cloth or sleeping mask between the headset and the bridge of your nose. This will create a small gap for your breath to escape through and reduce fogging on your lenses. Some companies, such as VR Cover, offer removable, machine-washable cotton headset covers. These often absorb sweat and oils better than the faux leather that many headsets come with, and can be replaced when they become too dirty.

Clean your lenses, face cushion, and headphones at least once a month. Clean your face with a skin-safe anti-bacterial wipe before playing. Use a fan or air conditioning when you play to reduce sweating. Keep your headset in a drawer or cloth bag to protect it from dust. Place a cloth over the bridge of your nose to reduce fogging. Buy a removable headset cover.
Article: Go to https://www.investor.gov/tools/calculators/compound-interest-calculator to access the compound interest calculator. This calculator is provided by the Securities and Exchange Commission's website Investor.gov. On the page, you will be asked to input several variables. These should be entered as follows:  Current principal: this is how much you initially invested or the original amount on your loan. An investment should be entered as a positive number while a loan amount should be entered as a negative number (using a "-" sign). Monthly addition. If you regularly add an amount to your investment or pay down your loan at regular intervals, input the amount paid each time as a positive number. Years to grow. This is the time period you are looking at in years. This can also be the life of your loan. Interest rate. Input the interest rate your investment earns or the amount you pay on your loans. This is the annual rate. Compound interest __ times per year. Input 1 for annual compounding, 2 for semiannual, 4 for quarterly, or 12 for monthly, depending on how your investment or loan compounds. This information should be available on an investment prospectus or loan document. To calculate interest earned on investments, start by inputting the amount that you initially invested. Be sure to include any payments you make on a monthly basis in the "monthly addition" box. Then, enter the number of years you want to track investment growth over. Next, input your interest rate. This can be an expected interest rate if you are unsure. Finally, input how many times your investment interest is compounded each year. You can play around with these variables and use them to compare different investment opportunities or different interest rates and compounding frequencies. Because this is technically an investment calculator, finding interest on loans is a bit different. First, you'll have to enter the principal on the loan as a negative number. This lets the calculator know that you owe the money instead of owning it. For monthly addition, input how much you are able to pay down the loan each month. This can be a minimum payment, a budgeted amount, or any other amount that you can pay each month. Input the rest of the variables as normal. If your result is negative, you will still owe money at the end of the timeframe. However, a positive number reflect that you can pay off the loan in this way by the end of the period. You can also use this calculator and some guesswork to determine the right monthly payments for you. Say, for example, you owe $20,000 on a credit card that charges 20% interest compounded monthly. You want to pay off the card in two years, but don't know how much to pay each month to do.  Start by guessing a proper monthly payment. For example, $800. By inputting this data, you'll see that you'll still owe $6,336.39 at the end of the two years if you pay $800 each month. Increase your guess. For example, $1000. This one is much closer and leaves you with only about $523 to pay at the end of the two years. Continue this process until you arrive at an approximate monthly payment that suits your needs.

Article: Piercing your lip will be painful, and the piercing may cause bleeding. The area may be tender, swollen, and bruised for several days afterward. Lip piercings can take anywhere from 6 to 10 weeks to heal fully, so be prepared for multiple daily cleanings during that time, plus regular upkeep after that. Cleaning your lip piercing is pretty straightforward, but it will require non-iodized salt, alcohol-free mouthwash, and a mild, fragrance-free soap. Pick up a new toothbrush as well—one with soft bristles—and replace your old one after getting your piercing. Before getting your lip pierced, know what to look for regarding infections. Symptoms include pus, green or yellow discharge, tingling or loss of feeling around the piercing site, fever, and excessive bleeding, pain, redness, and swelling. Leave the jewelry in if you suspect an infection, but seek medical attention immediately. Body jewelry often contains nickel, which is a common allergen for many people. Symptoms will likely appear within 12 to 48 hours, and can include itching and swelling, crusty or scaly blisters, and redness, rash, or dry skin.  Your lip piercing won’t heal properly if you are allergic to the jewelry, so go to the doctor immediately if you suspect an allergy. If you can’t wear necklaces, earrings, rings or bracelets containing nickel, you won’t be able to wear it in your lip, either. Look for jewelry labeled “surgical steel” or “nickel free.” In addition to nickel, some people may be allergic to copper or brass. These 3 base metals cause the majority of allergic reactions to jewelry.
