Code books can be stolen, lost, or destroyed. Modern cryptoanlaytic techniques and computer analysis can oftentimes break even strong codes. Even so, codes can condense long messages into a single signal word, making them great time savers. Codes serve as good pattern identification practice. This skill can be put to use when encoding, decoding, enciphering, or deciphering messages. Codes are naturally used between close friends. Inside jokes could be thought of as a kind of "code." Try developing your code language with your best friends. Knowing the purpose of your code will prevent unnecessary work. If your goal is to save time, you might only need a few specific code words. If you're trying to encode detailed messages, you may need to develop a code book that is more like a dictionary. Select common phrases that occur in the messages you want to encode. These are prime targets to be condensed in a code word. Codes can be further complicated by using several different codes in rotation or combination. However, the more codes used, the more code books necessary for decoding. Condense common phrases, like "Reading you loud and clear," to something like "Roy." For every conceivable word in your encoded messages and common phrases as well, designate alternative code words. Sometimes, partial code can obscure a message sufficiently. For example, if "walk" means "tango" and "museum" means "restaurant" and the previously used code word "Roy" holds its value, Message: About yesterday. I wanted to say, Roy. I'll tango to the restaurant as planned. Over and out. Meaning: About yesterday. I wanted to say, reading you loud and clear. I'll walk to the museum as planned. Over and out. Use the code words in your code book to encode messages. You may find that you can save yourself time by leaving nouns (like names and pronouns like I, me, she) as plain text. However, this decision depends purely on your situation. Two-part codes apply two different code books to encode or decode a message. These are much stronger than one-part codes. A key message, group of words, letters, symbols, or a combination of these can be used to encode information. The recipient of your message will also need this key phrase or key of letters/symbols to decode the message. For example, with the key word "SECRET," each letter of your message would convert to the number of letters between it and the corresponding letter of the key word. As in, Message: Hello Encoding:/H/ is 11 letters away from the key /S//e/ is the same (zero) as the key /E//l/ is 9 letters away from the key /C/And so on... Coded Message: 11; 0; 9; 6; 10 As you receive coded messages, you'll have to make use of your code book or key word/phrase to make sense of them. This may be difficult at first, but will become more intuitive as you become more familiar with the code.

You can use dividers if you want a perfect circle. As you keep on practicing, you will be able to draw a perfect circle without any need of dividers or anything else. (Do not put too much pressure on the pencil while drawing this as this is "just" a baseline and you will have to erase it when you're done.) (Draw the second line a little lower from the diameter of the circle.) The two points where the circle and the horizontal line touch, mark the point where the jaw will start and the tip of the vertical line will be the tip of the chin. This line should be parallel to the first one. The eyes will be placed between the two of them. Start off with two lines on the horizontal baseline on the top, shaped like an arch. The lower lines of the eye should be straighter than the ones on the top but should still not be too straight. The lower lines should be shorter than the ones on the top but not too short. Add some eyelashes, both on the top line and the lower line. The lower tip of the oval should "slightly" touch the lower eyelid when the upper part of the oval should look like it was "half-covered" by the upper eyelid. (Check the image for this step for some more help.) Although, if you want to give her a "surprised" look, the upper part of the oval nor the lower part should not touch the eyelids "at all". Add little circles inside the eyes. These will be the sparkles. Then add the pupils. The pupils should be large but if you want to give her a "frightened" look, the pupils should be small. This is the nose. The mouth will be placed on the vertical line and just under the nose. But before erasing, mark the point where the mouth will be so it will be easier. Don't panic if you had erased the lines before marking the spot, it is easy to understand where it should be. Start with a short line, shaped like an arch. Then draw the same line, but this time upside down so that it looks like a pout. Add another little line under the mouth. This is the lower lip. Eyebrows can be straight (if you want an innocent or afraid look) or they can be arch-shaped (if you want a serious or neutral look).

One-sentence summary -- Start off with a circle for the head. Now draw a vertical line that divides the circle into half that is a little longer than the diameter of the circle and a horizontal one that the two lines make a 90 angle. Draw the chin with the help of these two lines. Draw another horizontal line a little higher than the first one. Drawing the eyes is the most difficult of them all. For the eyes, draw two ovals between the two lines. Put a little line on the point where the first vertical line cuts the circle. Before adding the mouth, you should erase the base lines. Draw the mouth. Add the eyebrows.

If you're concerned that you are getting too much salt in your diet, discuss your concerns with your doctor or a registered dietitian. They can help you determine whether you need to cut back on your sodium intake, and how much sodium you should be getting in your diet. Your doctor or dietitian may be more likely to recommend that you cut back on your salt intake if you have certain health issues, like high blood pressure or diabetes. Doctors recommend that most healthy adults should consume no more than 2,300 mg (0.08 oz) of salt per day. If you eat a standard American diet, chances are that you are eating far more than the recommended dosage. You can cut down on your salt intake with a few simple changes: Trade pre-packaged foods for fresh ones. Pre-packaged meats, such as luncheon meats, bacon, or sausage, are often loaded with additional salt. Look for products that are labeled "low sodium." Check pre-packaged food labels carefully for sodium content. Cut salt out of recipes, when you can. Try spicing up your food with other seasonings, like salt-free pepper or garlic powder, instead. Potassium, like sodium, is an important electrolyte that your body needs to stay healthy. Most people eat too much sodium, and not enough potassium. Getting enough dietary potassium can help your body get rid of excess sodium. Good sources of potassium include: Baked potatoes, with the skin left on. Avocado. Bananas. Leafy green vegetables, like spinach or Swiss chard. Dairy products, like yogurt or milk. Beans and lentils. . Dietary Approaches to Stop Hypertension, or DASH, is a diet that focuses on lowering your sodium intake and using healthy portion sizes. Depending on your needs, your doctor or dietitian may recommend a standard DASH diet or a lower sodium DASH diet. On a standard DASH diet, you can eat up to 2,300 mg (0.08 oz) of sodium per day. On a lower sodium diet, you can eat no more than 1,500 mg (0.05 oz) of sodium per day.
