Calcium

You have more calcium in your body than any other mineral. Calcium has many important jobs. The body stores more than 99 percent of its calcium in the bones and teeth to help make and keep them strong. The rest is throughout the body in blood, muscle and the fluid between cells. Your body needs calcium to help muscles and blood vessels contract and expand, to secrete hormones and enzymes and to send messages through the nervous system.

It is important to get plenty of calcium in the foods you eat. Foods rich in calcium include diary products such as milk, cheese and yogurt, and leafy, green vegetables. The exact amount of calcium you need depends on your age and other factors. Growing children and teenagers need more calcium than young adults. Older women need plenty of calcium to prevent osteoporosis. People who do not eat enough high-calcium foods should take a calcium supplement.

About Korean Food

Korean Food is casually represented by bulgogi and kimchi. In fact, however, Koreans are proud of their diet, quite varied and full of nutrition. It is richly endowed with fermented foods, vegetables and grains, soups, teas, liquors, confectionery and soft drinks. Kimchi and doenjang paste made of soybeans are the best-known examples of Korean fermented foods, and these have recently become highly valued for their disease-prevention effects. Korea boasts hundreds of vegetable and wild green dishes. The Korean meal is almost always accompanied by a big bowl of hot soup or stew, and the classic meal contains a variety of vegetables. Korean foods are seldom deep-fried like Chinese food; they are usually boiled or blanched, broiled, stir-fried, steamed, or pan-fried with vegetable oil.

Korean Etiquette

Korean families usually eat rice, soup, and three to four side dishes including the sine qua non, kimchi. From each person's left are arranged rice, soup, spoon, and chopsticks, while stews and side dishes are placed in the center to be shared by all members. Koreans use a spoon to eat rice, soup, and stews and chopsticks for rather dry side dishes, but spoon and chopsticks are not used simultaneously. Koreans also do not hold their bowls and plates while eating. When the meal is over, the spoon and chopsticks are placed back where they were. Koreans generally believe that sharing food from one bowl makes a relationship closer. Still, one who does not wish to share the one-for-all dish can courteously ask the host for an individual bowl or plate. Today most Korean restaurants offer individual bowls and plates. In the olden days, talking was not allowed at the dinner table, but today, eating etiquette has become more liberal. Chopsticks may be used to eat rice.

Use by drivers

Using Mobile phone while driving is common but controversial. Using a mobile phone while driving is an obstruction to vehicle operation that can increase the risk of road traffic accidents, but different studies have found different relative risks (RR).

Meta-analysis by The Canadian Automobile Association and The University of Illinois found that response time while using both hands-free and hand-held phones was approximately 0.5 standard deviations higher than normal driving.

Other research has found that using a mobile phone while driving may reduce and also divert the driver's concentration and reaction time. People in or near their 20s who use a mobile phone while driving have the same reaction time as 72-year-olds.There is a law which restricts drivers under the age of 18 from using a mobile phone at all. According to this law $20 fine for the first offense and $50 fines for each subsequent conviction…
