Article: There are very few foods that are naturally high in vitamin D. If you can find some that are and consume them on a regular basis, you will optimize your body's ability to naturally absorb vitamin D. Foods that are naturally high in vitamin D include:  Salmon Tuna Mackerel Sardines Cod liver oil Eggs, cheese, and beef liver contain small amounts of vitamin D Because foods that naturally contain vitamin D are hard to come by, there are regulations in many places in the world (including the United States and Canada) that certain foods be fortified with vitamin D prior to being sold at the grocery store. Foods fortified with vitamin D compose the majority of vitamin D in most people's diets. These foods include:  Milk Margarine Some breakfast cereals Some brands of orange juice Some bread products Some yogurt Everybody can benefit from a high-quality vitamin D3 supplement, which allow you to benefit without risking skin damage from sun exposure. Unfortunately, the current RDA's are very low to benefit the body and there is no consistent agreement among health organizations about how much to take. The maximum daily safe dose for adults is 4,000 IU (though some research suggests that 10,000 IU may still be safe). Infants and children should take lower doses (0–6 months, maximum 1,000 IU; 7–12 months maximum 1500 IU; 1–3 years maximum 2500 IU; 4–8 years maximum 3,000 IU).  These recommendations may also change if you have an illness that interferes with your body's natural ability to absorb vitamin D. Consult your doctor if you need a higher dose. Always take vitamin D3 (cholecalciferol), not Vitamin D2. Vitamin D2 is poorly absorbed.  Remember that other supplements such as multivitamins and fish oil can contain vitamin D. Be sure to factor that in to ensure that you do not take too much. You can get both flavored and flavorless supplements that are drops. Sometimes, one oral drop = 1,000 IU. This makes it easy to supplement with vitamin D.

Article: Sure, you may think that you really "need" a huge HD TV, but would you really suffer if you got a TV of a smaller size, or stuck with your old for a while, instead? Do you really need designer shoes or sunglasses, or would you be just as happy with a cheaper pair? Do you need to spend $90 every time you go out to dinner with your beau, or can you go somewhere a little bit cheaper, or have a romantic night cooking at home instead? Realizing that you don't really need all those things you think you need will definitely help you live within your means. It's okay to splurge on something you don't really need once in a while, but you shouldn't make a habit of it. And when you do splurge, you should be conscious that your life would be just as good without that thing. So maybe your neighbors just got a swimming pool or built an addition onto their home; but they may make twice as much money as you do. If you get caught up in trying to keep up with everyone around you, then not only will you never be happy, but you will also never be able to live within your means because you'll be too busy trying to maintain an image that you can never fully live up to. Sure, your best friend's new designer jeans look amazing on her. Be happy for her cute new look instead of being jealous and wishing you can afford the same. Jealousy is guaranteed to make you an unhappy person -- and to never be satisfied with what you have. " Being rich doesn't have to mean driving a BMW and vacationing in Capri every fall; it can mean having enough money to keep your family and children happy, and to have some spending set aside for fun with your significant other and some light travel, too. Once you see that this can be your own definition of "rich," you will be able to relax and stop worrying so much about how other people perceive your wealth. So you invite some friends over for some nice wine instead of spending money at a crowded bar. You and your significant other take a road trip to Portland instead of flying there. Does this really decrease your quality of life? Absolutely not. You'll still be doing the things you love -- you'll just be doing them a bit differently. Don't think that you'll be making your life worse if you spend less money. In fact, spending less money can increase your quality of life, because doing so will make you less stressed out about wasting money, and you'll feel more at peace with your decisions. Instead of focusing on what you wish you had -- a new car, a fancy suit, a larger house -- focus on all of the things you are lucky enough to have. You may hate your TV, but you love your computer. You may wish you had a new coat, but you have so many great sweaters. Make a list of all of the things you do have, and don't just limit the list to the material things -- you may be grateful for an amazing significant other, wonderful children, or the amazing place where you live. Being aware of all of the things that you do have will make you less likely to spend impulsively to make up for anything that you feel is lacking in your life.
Question: What is a summary of what this article is about?
Distinguish between what you want and what you need. Don't even bother trying to keep up with the Joneses. Change your definition of what it means to be "rich. Know that spending less money will not decrease your quality of life. Be grateful for what you do have.
Article: Running multiple programs and apps at once uses a significant amount of your laptop’s memory, causing it to run slowly. Reducing the number of programs and apps you have open may improve your laptop’s speed. Look for programs that you've minimized but haven't actually closed. Each tab in your web browser requires a small amount of memory to run. The more tabs you have open, the more memory your laptop is required to devote to running the web browser. Limiting the number of tabs you have open at a time can enhance the speed of your laptop.  After you’re finished with a tab, close it. If you are keeping it open as a “reminder” to do something, write yourself a note or send yourself an email instead. Laptops benefit from regular (~1x/week) restarts. Restarting may significantly improve your laptop’s speed. Removing programs, apps, and files you no longer use will free up space on your laptop’s hard drive. Try looking your your applications folder for old or unused programs to delete or uninstall.
