In one sentence, describe what the following article is about: As of October 2016, a brand new Samsung J7 goes for about $250. You may see some variation in that price with different retailers due to sales, but not by much. If you find one that’s only $150 and claims to be brand new, it’s probably not real. Samsung’s website has a list of all businesses authorized to sell its products. Visit http://www.samsung.com/us/peaceofmind/authorized_resellers.html to view the current list. If you’re buying a phone online from an individual on a site like eBay or Craigslist, you should always check the IMEI before buying. If a seller doesn’t want to give you the IMEI, you shouldn’t trust that seller.
Summary: Look at the price. Shop with one of Samsung’s authorized dealers. Ask the seller for the IMEI.

It's been shown that single people exercise more than married people. This may be because they have more free time or because they are more concerned about their appearances. Either way, take advantage of your single status to get healthy and enjoy life to the fullest. Because they rely more on themselves and have to deal with society's negative opinions about their relationship status, single people tend to be stronger and more resilient than couples. The next time you feel bad about not having a partner, remind yourself that you are a better person because of it. There's a tremendous amount of freedom that comes along with being single. If you were in a relationship for a long time, you may have forgotten how liberating it can be to make all of your own decisions, without having to worry about another person's opinion. Now that you are single, enjoy your freedom in these simple ways:  Travel when and where you want. Create a schedule that works for you. Decorate your apartment or house the way you like it. Eat the foods you like. Go out, stay in, or have people over as you prefer. Single people tend to value meaningful work more than people who are in relationships. If you want to be happy while single, it might help to commit more of your time to something you genuinely care about, whether it's your job or volunteer work.  Being single can make it much easier to truly commit yourself to your work because you don't have to worry about fulfilling the needs of your relationship. If you plan on being single for a long time, look for a job that gives you a sense of purpose and makes you want to get out of bed every single morning. If your life is already that fulfilling, being single won't feel like a void at all. Spending time alone can make you more creative and help you see the world from a different perspective. Take advantage of your alone time to pursue your creative passions, whether it's writing, painting, or just taking the time to admire the clouds in the sky.  Trying new things is one of the best ways to fend off loneliness when you're single. Take advantage of your ability to do whatever you want whenever you want and discover new interests and passions to keep your life exciting. Once you've learned how to survive when you are not in a relationship, you can decide if you would like to stay single or find a partner. Either choice is perfectly acceptable, so don't let others pressure you. Don't rush into a relationship that isn't right. The relationship should be reciprocal, and you shouldn't have to give up your personal identity.

One-sentence summary -- Live a healthy life. Be proud of your strength. Do what you want. Devote yourself to your passions. Pursue healthy relationships, if you want.

Q: There are many techniques one can employ to achieve an artistic effect, and knowing these will make it easier for you to translate your artistic knowledge to a living canvas. Taking collegiate courses in fine arts will ensure you have a good grounding in these principles. You will need to prove your artistic worth before another tattoo artist is willing to invest time in you as an apprentice. Your designs should be similar to common tattoo art, as well as anything that shows off skillful composition and coloring talent. You can also showcase your talent and dedication by performing henna tattoo designs imitating permanent tattoo designs. This will also show to the master tattooist you want to apprentice under that you already have an understanding of what it means to translate a design to the pliant medium of skin. Volunteer your services as a face painter at a school festival, local parade or festival, or at a nearby carnival. This will give you first hand experience as to the procedure, atmosphere, and techniques from other tattooists. Also, having a tattoo of your own will show your clients that you can empathize with the experience, which will help put them at ease.
A: Become skilled in drawing and coloring. Build your portfolio. Attempt non-permanent body art. Get a tattoo yourself.

Problem: Article: In many parts of the world, food manufacturers are required by law to provide nutritional information on packaged food products. This information is presented in the form of a chart, which can usually be found on the back or side of the package. If you’re curious about what you’re eating, the nutrition facts label is where you should look first. A food’s nutrition facts can tell you everything you need to know about what’s in it, including a comprehensive ingredients list and an overview of each of the major macronutrients. When assessing a food’s nutritional value, you should look at 3 things: protein, carbs, and fat. These macronutrients account for all of the calories in the item (aside from calories from alcohol). As a result, the exact amount of each macronutrient indicates what proportion of the total calories they make up. Alcohol also contains a significant number of calories. Each gram of alcohol is about 7 calories. A gram of protein is estimated to contain about 4 calories. A gram of carbohydrates also has 4, and a gram of fat is worth a whopping 9 calories. If the item you’re eating contains 20g of protein, 35g of carbs, and 15g of fat, this means you would multiply 20x4, 35x4, and 15x9 to find the number of calories contributed by each macronutrient—80, 140, and 135, respectively. Nutrients are always measured in grams. Make sure you’re using the right standard when calculating food calories yourself. Now that you know how the calories are divided up, add together each individual count to get the combined calorie count for one serving of the item. Going off the previous example, 80 + 140 + 135 = 355 calories. This number should correspond with the estimate displayed on the item’s packaging.  Breaking down the calorie count by macronutrient rather than simply reading it off the box allows you to see not just how many calories are in a certain type of food, but how to make them part of a balanced diet. 355 calories might not sound like a lot, but if you’re trying to eat less fat, you might be alarmed to discover that fat grams account for nearly half of the total. Be aware that the figures for both the calories and macronutrients represented in the nutritional facts only indicate a single recommended serving. If there are multiple servings included in the package, the total number of calories will actually be much higher. This can be an important fact to keep in mind if you’re tracking calories as part of a diet or exercise plan. For example, an item containing 355 calories per serving and with 3 servings per package makes the total 1,065 calories. According to dietitians and other food experts, 46-65% of the total calories you consume on a daily basis should come from carbohydrates, 10-35% from protein, and 20-25% from fats. The recommended daily value (DV) column featured in the nutrition facts will tell you how much of those proportions you’re getting from the item.  A snack containing 35g of carbohydrates, for instance, provides roughly 12% of your recommended daily value of around 300g.  Daily values are averages based on dietary recommendations for adults who eat around 2,000 calories a day.
Summary:
Locate the nutrition facts on the item’s packaging. Note the amount of protein, carbohydrates, and fat contained in the item. Multiply each macronutrient by its caloric equivalent. Total the calories for each macronutrient. Take serving size into account. Compare the calories of different nutrients to their recommended daily values.
