These handheld tools allow you to reach right against the edge of the wall. If using an orbital sander, you probably already reached the walls. In this case, you can skip this section, and remove the finish at the corners with any handheld sander. For this small remaining area, you may be able to skip some of the steps you used on the whole floor. That said, you will need to start with a coarse grit to remove the old finish. Move the edge sander back and forth along the wall in small triangular movements. This is less likely to leave marks than a side-to-side motion. Most tools are designed so moving right (clockwise) along the wall is easier than the other direction. You can now skip straight to 80-grit sandpaper. Sand carefully until the edge matches the rest of the floor. If you want to finish with 100-grit sandpaper, you'll need special techniques to avoid burning the floor and paper. You'll need a sander with a slow speed setting, and preferably an "open coat" sandpaper. Your floor is now ready to be stained and/or waxed. Try to keep dirt, abrasives, and heavy objects off the floor until it is finished.

Q: While the following steps describe actions that are generally helpful for people with high blood sugar and associated health problems, they will not be as effective as specific recommendations tailored to your health problems and characteristics. Visit your doctor or doctor-recommended nutritionist regularly to check on progress and keep an eye out for possible health problems that result from high blood sugar. While exercise reduces blood sugar in the long run, it can actually increase your blood sugar in the short term by encouraging your body to produce glucose (sugar) to fuel your muscles. If you have diabetes or other health issues that require testing your own blood sugar, it's important to check your blood sugar levels before you begin exercising and about every 30 minutes during exercise. A doctor or drugstore may be able to provide you with a blood glucose meter or testing strip for testing your blood sugar. If you are diabetic, it's important to adapt your exercise routine to the results of a blood sugar test, as mentioned above. Decide whether exercising is safe at this time using these instructions, or the instructions your doctor provides for your specific case: If you blood sugar is lower than 100 mg/dL (5.6 mmol/L), raise your blood sugar before exercising. A small snack containing carbohydrates should accomplish this, such as fruit or crackers. If you do not eat any carbohydrates and exercise anyway, you risk experiencing shakiness and anxiety, falling unconscious, or even entering a coma. If the test result is between 100 and 250 mg/dL (5.613.9 mmol/L), no action is required unless your doctor instructed you otherwise. Continue to exercise. If you are diabetic, and especially if you have type 1 diabetes, you should not exercise when blood sugar is high without first testing for ketones. These are substances that cause serious health problems if they build up, and exercising might increase their levels. Test your urine for ketones using as ketosis test strip from a drugstore, following the instructions carefully. Do not exercise if ketones are present, and test regularly if ketone levels are moderate or high. Seek medical attention immediately if you have very high ketone levels or if the ketone levels don't drop after 3060 minutes. If your blood sugar is higher than 300 mg/dL (16.7 mmol/L), do not exercise. Wait for 3060 minutes without eating, and test again to see if your blood sugar has dropped to a level that is safe for exercising. Let a doctor or nurse know if you experience this high level of blood sugar frequently or for several hours at a time. . Exercise helps convert glucose into energy, makes your body's cells more sensitive to insulin, and reduces excess fat, which is associated with high blood sugar. The more active you are, the less likely you are to have problems with high blood sugar. Aim for at least 30 minutes of moderate exercise a day, for at least 5 days a week. In total, you should exercise 150 minutes or more each week. Try to find an exercise that you enjoy; this way you will be more likely to stick with it in the long run. Fast walking, swimming laps, or bicycling are common choices. If you have diabetes or are at risk for diabetes, keep an eye out for signs that the exercise may be causing health problems. If you feel faint, have chest pain, suddenly feel short of breath, or notice blisters or pain in your feet, stop and call your doctor.
A: Consult a doctor about an exercise plan. If you have diabetes, check your blood sugar levels before and during exercise. Decide how to exercise based on the results of your blood sugar test. Perform a ketone test if your blood sugar is above 250 mg/dL (13.9 mmol/L). Perform frequent, moderate exercise Stop exercising and call a doctor if you experience pain or blisters.

Article: Marginal zinc deficiency is relatively common, with about 2 billion people worldwide affected. Marginal deficiency results in poor growth, poor physical and mental development, and increased risk of infections. There are a number of risk factors for marginal zinc deficiency including: Premature and low-birth-weight infants or older breast-fed infants and toddlers who do not get enough zinc-rich foods Children and adolescents Pregnant and breastfeeding women, especially younger women Patients receiving a form of intravenous feedings known as total parenteral nutrition Malnourished or undernourished children and adults People with severe or chronic diarrhea Individuals with malabsorption syndromes or digestive and liver disorders People with Celiac disease, short bowel syndrome, Crohn's disease, ulcerative colitis Alcoholics with alcoholic liver disease Individuals with chronic renal disease and sickle cell anemia Older adults (over 65 years) Individuals on specific medications that interfere with the absorption or function of zinc Strict vegetarians Severe zinc deficiency is relatively rare. It is usually the result of a rare genetic disease called acrodermatitis enteropathica. In these cases, symptoms include slow growth and development, delayed sexual maturation, skin rashes, severe diarrhea, deficiencies of the immune system, poor wound healing, poor taste sensation and poor appetite and clouding of the cornea. If you believe you have this disease, go see your doctor for tests. Though zinc is important for your body's overall health, you want to make sure you get the right amount. It is difficult to overdose with food alone usually an overdose occurs from taking too many supplements and/or taking supplements in addition to a high-zinc diet. Excess zinc can cause significant health problems including nausea, vomiting, loss of appetite, cramps, diarrhea and headaches. High levels of zinc can interfere with copper and iron levels and this can cause copper and iron deficiency anemias. Always talk to your doctor and be aware the some multivitamins may include zinc.
