INPUT ARTICLE: Article: Coccyx cushion treatment will be most effective if you can use the cushion in the car, at home, at work and everywhere else you need to sit down. You can purchase several inexpensive cushions or opt for one that can travel with you and be used everywhere. Consistency is key to treating your tailbone pain with a coccyx cushion. Be aware that one cushion may not be suitable for all scenarios. For example, a cushion may help while you are sitting at your desk, but it may not be as effective while you are driving. Try using a cushion in different situations to see when it provides the most benefit. Use the coccyx cushion in a chair with a back that will give you extra support. The cushion naturally helps improve your posture by slightly elevating your hips, and sitting in a chair with a back will help you sit up straight and eliminate pressure on your spine and pelvis. When using a cushion on a chair that is a comfortable height for you, your thighs may be slightly higher than usual. To offset this difference, try using a footstool to make sure your lower body is still in a comfortable position. If the chair is adjustable, then you can also adjust the height of the seat to make yourself more comfortable. Do not use a coccyx cushion with other cushions. Adding extra pillows or cushions will cause you to sit unevenly and in turn, distribute your weight and pressure unevenly, which is unhealthy for your back. The placement of the cushion on the seat can either be flat or slightly slopping. This is most people's preference. If you need extra height, purchase a thicker coccyx cushion instead of adding extra pillows or padding. If you are putting the cushion on a very soft seat, like couch or plush chair, put a rigid board under the cushion for support. You can add flat ice or hot packs to your coccyx cushions for hot or cold therapy. Wrap the packs in towels and place one on either side of the cut-out area in the cushion. Some cushions may come with gel insert that you can warm up or freeze before reinserting them and using the cushion. Consult with your physician about whether the effects of ice or hot packs would be beneficial for you. Try to get a coccyx cushion with a removable cover that can be machine washed. This will help you keep your cushion is clean and sanitary. If the coccyx cushion isn't providing sufficient relief to your tailbone pain, then try a different one. For example, you use a coccyx cushion that is made of soft foam and find that it's not alleviating the pain, upgrade to a cushion made of firmer, denser foam for more support. Cushioning is an individual need, so your cushion needs will be unique.

SUMMARY: Use the cushion everywhere. Sit in a chair with a back. Place the coccyx cushion directly on the seat. Add ice packs or hot packs for added relief. Keep the cushion clean. Upgrade your cushion if necessary.

INPUT ARTICLE: Article: The rules of polite social interaction in Japan are complex, and may be very different from what you are used to. Before moving to Japan, get an up-to-date guidebook, chat with someone who knows Japanese culture well, and read blogs about life in Japan. Minimize misunderstandings and culture shock by familiarizing yourself with Japanese etiquette. Just a few things to keep in mind include: Tipping for service is not usually done, and may be considered impolite. If you are invited into someone's home, you should always bring a gift for your host. The exchanging of business cards is an integral part of any introduction in a professional setting, and it is impolite to put away the other person's business card until you are done conversing. Knowing the Japanese language (or at least the basics) will make it much easier for you to live and work in Japan. Before moving to Japan, consider signing up for a course, taking private lessons, or using language learning software like Rosetta Stone or Duolingo. The best way to get familiar with Japanese culture is to experience it. Ask a friend, a coworker, or a classmate for advice on interesting things to see and do, or see if they are willing to show you around. Take time to explore the area where you live, and get to know your new neighbors. If you know any other expats from your own country who have more experience with life in Japan, reach out to them. They may be able to help you connect with your new home and feel more comfortable.

SUMMARY: Read up on Japanese customs and etiquette. Take Japanese language lessons. Explore and try new things.

INPUT ARTICLE: Article: Look at the first digit of the number (the one on the left, with the highest place value). Mentally double that digit and write it down. The answer will be the first one or two digits of your final answer. Example: Find the double of 872. The left digit is 8. The double of 8 is 16. If the second digit to the right is 5 or greater, you will need to add 1 to the value calculated in the previous step. If the second digit is below 5, you do not need to add anything else to the previous value. Doubling any digit between 5 and 9 will result in a two digit number, which makes this step necessary. Doubling and digit between 0 and 4 will result in a single digit number. Example: The second digit in 872 is 7. Since 7 is greater than 5, you need to add 1 to the sum of the previous place value. 16 + 1 = 17 This means that your final answer will begin with 17. Return to the second digit and double it. This value will be the next digit in your final answer. If the value calculated in this step is two digits, ignore the digit in the tens place and only write down the digit in the ones place. Example: The second digit of 872 is 7. The double of 7 is 14. Ignore the tens place (1) and only save the value of the ones place (4) for your final answer. This 4 will appear in the middle of your final answer. Continue through the rest of the digits in the same manner, moving from left to right, until you double the final digit in the "ones" place value. Example: For this problem, there is only one more place value to work with. The final digit of 872 is 2. Since 2 is less than 5, you do not need to add anything more to the sum of the middle place value. The double of 2 is 4. This will be the final digit in your answer. Write all of the calculated values of each place position side by side. This should be your final answer. Example: The first part of the answer is 17. The middle digit is 4. The final digit is 4. When written together, that gives you an answer of 1744. Therefore, the double of 872 is 1744.

SUMMARY:
Double the left digit. Look at the second digit. Double the second digit. Repeat toward the right. Write it out.
