Fresh outdoor air helps clear your mind, while exercise promotes blood flow and makes you feel more energetic. Go for a brief walk, do sets of push-ups or jumping jacks, or engage in your favorite sport or physical activity.  If you do exercise or play a sport, make sure you don’t feel too sweaty, tired, or uncomfortable afterward. It’s best to stick with a moderate energy activity instead of a vigorous one. For instance, you could shoot a few baskets, but it might not be a good idea to play an actual game of basketball. If the weather isn’t good or if you don’t want to exercise outside for another reason, consider including some indoor physical activity. Even marching or jogging in place for a few minutes should give you a quick energy boost. Clutter such as loose papers, coffee mugs, and trash can be distracting, and prevent you from being able to fully focus and relax while studying. Take advantage of break time to throw away trash and remove items you don’t need from your desk. At the same time, keep in mind that this should be a break. If cleaning your study area seems like a long or demanding process--something to dread--it might be best to skip this activity during your break time and save it for after you finish this study session or before you start tomorrow’s session. Talking with someone in person or over the phone helps break up the monotony of quiet studying, and distracts you from your studies when you need a break. Just make sure you’re able to stop talking once your time is up. Choose someone who will be understanding and willing to end the conversation early--a parent, for instance, or another friend who can coordinate their study schedule with yours. Briefly explain that you’re on a time limit, set your timer as usual, and avoid heavy conversations that are likely to extend past your break time. Healthy snacks such as nuts, fruits, and vegetables are loaded with antioxidants, vitamins, and minerals that give your brain and body the nourishment it needs to refuel so you can get back to studying.  Consider snacking on a handful of nut or seeds for some energizing vitamin E, or biting into a bar of dark chocolate (which also contains antioxidants and a small dose of caffeine). Since these foods tend to be high in calories and fat, however, you should stick to only an ounce a day.  Other options might include whole grain popcorn, crackers, or chips, avocados, and blueberries. . These exercises naturally help you feel calm and relaxed, and are effective at refreshing your brain so it can absorb more information.  After setting your timer, sit somewhere quiet and comfortable, with your eyes closed or fixed on a blank space (like an undecorated wall). Take deep breaths--inhaling over five seconds, holding for five seconds, and exhaling for five seconds--and focus on the way it feels to have your lungs fill with and release the air. There are other forms of meditation you can also dabble with. For example, you might try mantra meditation, in which you’ll repeat a short, calming word or sound--like “om”--to help clear your mind and release tension. Read an enjoyable book, magazine, or other content unrelated to your studies. This helps refocus your brain on another topic so you can return to your studies later on with a fresh perspective. Like any other break activity, you should make sure that you choose reading material you can break away from easily when your timer goes off. This is not the time to pick up that captivating, page-turning novel you’ve been dying to read. Instead, consider something like an anthology of short stories or a magazine. Research shows that listening to your favorite tunes encourages the release of feel-good chemical dopamine, which can make you feel rewarded after intense study sessions. If you’re the dancing type, consider dancing around or singing as you listen to your music, too. Doing so could also provide some physical activity, which gets your blood flowing in a way that energizes the mind. Showering refreshes and invigorates your body and mind, and helps you feel more calm and relaxed. If you feel frustrated or tired, take a quick shower to reset your brain. Depending on how long your normal “beauty routine” is, you might want to save this for a break time happening later in the night, when you can skip the routine without worrying about leaving the house and being seen with your hair still unstyled and your clothes looking wrinkled. When you're studying at school or a place like a library, it isn't exactly easy or appropriate to go outside for a walk or get up and dance, so find things you can do that won't disrupt others. You might do some stretching, rest your eyes, get up to sharpen a pencil or ask your teacher to go to the bathroom or get a drink of water. You might take some time to do a little doodling or organize your backpack or study materials. Use your best judgment for what is ok to do on a break and ask your teacher if you're not sure about something. If your teacher doesn't seem to understand, try to explain that you learn better if you are able to take some study breaks.

Article: Raw beef is notoriously difficult to cut. However, you can alleviate some of the strain by placing the beef in the freezer. Partially freezing beef firms up the meat, making it easier to work with. Put your meat in the freezer for 30 minutes to an hour. The extra time you put into preparing it will make the cutting process that much easier for you. One thing about cutting beef while raw is that you're able to cut off potentially unwanted parts (like muscle and fat) without their flavour sinking into the rest of the cut during the cooking process. Slide your knife under the surface fat and take it off in a smooth motion. Take care not to go too deep with your cuts. Getting too aggressive with your fat trimming will result in the loss of good meat.  Membrane is a fine film over parts of some cuts, and can be peeled off with your hands.  Consider leaving some of the fat on your cut. Even if you want to keep your beef lean, a bit of fat will keep your cut of beef juicy. If you haven't yet cooked your beef, it's all the more important that you make your cuts consistent. If you're cutting pieces of different sizes, they'll cook at different rates. This will run the risk of undercooking (or overcooking!) parts of your beef. It helps to mark your cuts beforehand. Because consistent size is so important with pre-cooked cutting, you should get the measurements done before you set a knife to your beef. Setting your beef on a cutting board, cut down in a smooth, downward motion, much as you would with cutting cooked beef. Although raw beef is generally harder to cut, pre-freezing it partially helps ease some of the difficulty. If you plan on cutting the beef before cooking it, only cut it if you're planning on cooking immediately after. Slicing in advance will increase oxidation and make the meat taste off. Raw beef carries lots of bacteria with it. Whenever you're handling raw meat, it is strongly recommended you wash your hands thoroughly afterwards. Lather your hands with anti-bacterial soap under hot water for at least 30 seconds. Dry your hands off with a towel afterwards.
