If you have symptoms of anemia or think you may be at risk, it’s very important to see your doctor before attempting to treat or prevent it yourself. Different forms of anemia require different kinds of treatment, and some may be dangerous if not treated properly.  If you’re fatigued for no obvious reason, see your doctor. While fatigue doesn’t necessarily mean you have anemia, it is a common symptom of anemia and a variety of other medical conditions. Your doctor can run a variety of blood tests to determine whether you have anemia and what may be causing it. In some cases, they may need to take a sample of your bone marrow or do other tests to look for underlying causes of your anemia.  People with mild anemia may have no symptoms at all and may find out about it accidentally. For example, you might discover that you have low hemoglobin levels when you try to donate blood. If this happens, see your doctor. While dietary supplements can be helpful for certain types of anemia, not all anemias are caused by vitamin or mineral deficiencies. Taking supplements to treat or prevent anemia could be unhelpful or even do more harm than good depending on the type of anemia. Talk to your doctor before trying any new supplements.  For example, iron supplements can cause organ damage in people with sickle cell anemia.  Some supplements can interfere with medications you are taking. Before starting any supplement, talk to your doctor about your health history and give them a full list of medications and supplements you are currently taking.

Q: While you may be tempted to immediately log onto a search engine, slow down and write a “cheat sheet” on what you know about your long-lost friend.  Think about interesting details beyond name, occupation, and last city lived. Do they play any sports? Are they a member of any political organizations? What are their hobbies? What might they like to do online? If you think your long-lost friend has changed their name, through marriage or otherwise, think about the potential city where the name change happened. In most states in the United States, someone seeking a name change has to publish a notice in the local newspaper stating that the action for a name change has been filed.   You might want to include the name of such a newspaper on your "cheat sheet." An example would be to include the person’s first name + their favorite hobby + a city they once lived in. Think outside the box: A highly specific interest or characteristic of your friend may elicit a favorable search even if you don’t know your long-lost friend’s last name. Now that you’ve developed several search variations, you can turn to the search engine, Google. Enter your terms and click search.  Chances are good that you will find a social media profile connected to your long-lost friend; in 2016, almost 80% of the U.S population has a social network profile.   A social network profile for your long-lost friend may be connected to LinkedIn, Facebook, Twitter, Instagram, Pinterest, or perhaps a website less popular in the United States. (Xing has a global presence, and RenRen is prominent in China.)   If you don’t have luck on Google, consider using the next three most widely used search engines: Bing, Yahoo!, and Ask.. If your search successfully elicited evidence of your long-lost friend’s existence, congratulations. If the evidence came in the form of one or more of your friend’s social media profiles, you can attempt to connect to your friend through these profiles. The easiest way would be to use a platform for which you already have your own personal profile.  On LinkedIn, click Connect and/or Send InMail. On Facebook, add the person as a friend. On Twitter,  “follow” the person. Then “tweet” at your long-lost friend by copying their user name preceded by the @ symbol, and writing a message as your Twitter status.
A: Write down everything you know about the person you’re looking for. Combine these details into potential search terms. Apply your search terms to an online search. Study the results of your search.

Article: Consider this if you have books ranging from trade paperbacks to oversize art albums. Place the tallest books on the lowest shelf, placing smaller and smaller books as you move upward. This creates a tidy, organized appearance. On some bookcases, this is a necessity to adapt to the height of each shelf. This system looks great, but are best used if you have only one bookcase. In larger collections, they can make a book difficult to find. In addition, you need to consider that you may have to split books from a series, when they do not have the same colour. Here are a few sorting systems based on spine color:  One color per shelf (a blue shelf, a green shelf, and so on). If you're having trouble filling a shelf, wrap some of the books in kraft paper.  A gradual "rainbow" flowing from one color to the next, or from the most saturated colors to pastels. A pattern that creates a flag or other simple image when the whole bookcase is filled. This is time-consuming, but impressive. This is a great system if you consult your books frequently for research or reference. Keep the ones you use daily on the shelf at eye height. and a couple shelves below, where you can easily see and reach them. Books you only use occasionally go on the lowest shelves. Books that you almost never open go on the shelves above your head. If you have enough books to fill two or three bookcases, fill the most visible bookcase with the important books. If you have an even larger collection, this system may not work well. If you have a large number of books you'd like to read, why not give them their own shelf? Keep an empty shelf on the same bookcase so you can slot the finished books back easily. You might want to revisit your organization once you're through your reading list, but this can be convenient in the meantime. Fill the top shelf with books you read in early childhood, and move down adding books in the rough order you discovered them. This one works best for books with strong associated memories – and for people with strong memories as well. No matter which system you chose, you have the option of leaving one special shelf. Usually the most visible one, this is where you keep your first editions, your signed copies, or the books that have changed your life.
