Anybody who is over the age of six knows that there is nowhere safe for skateboarders to skate. Tis prevents young people from enjoying an active, energetic and adventurous patime.

Just watchva local street for a short while and note the steady stream of skaters speeding up and down the foot paths. Toddlers can be trampled on and old ladies can be knocked down as they struggle home carrying their cat food from supermarkets. Thunderous rattles are heard on our main roads each night as skaters travel without lights and without signs to oncoming cars.

Skateboarding is a serious sport that improves young people’s health. It increases fitness, improves balance and strengthens the joints in knees and ankles. Although it appears to be a solo sport, when groups practice together and compete to perform stunts or runs, they form firm friendships.

Young people should be prevented from becoming overweight couch potatoes. If they are actively involved in skating, they do not smoke, take drugs or break laws for fun.

Kids will always seek thrills and axcitement. They need to pracyice their 180, 360s. And Ollie’s free from restrictions. We must build skate parks in the suburbs so that streets are safe for small children and senior citizens, and skaters have spaces where they can race, chase, speed and soar towards the sun.

Antibiotics is a drug produced by certain microbes. Antibiotics destroy other microbes that damage human tissues. They are used to treat a wide variety of diseases, including gonorrhea, tonsillities and tuberculosis.

Antibiotics are sometimes called ‘wonder drugs’ because they can cure diseases such as meningitis, pneumonia and scarlet fever. But when the antibiotics are overused, or misused, these drugs make a person sensitive being attacked by a superbug.

Antibiotics do not always distinguish between harmless and dangerous microbes. If a drug destroys too many harmless micro-organisms, the pathogenic ones-the dangerous microbes-will have a greater chance to multiply. This situation often leads to the development of a new infection called suprainfection.

Extensive use of some antibiotics may damage organs and tissues. For example, streptomycin, which is used to treat tuberculosis, has caused kidney damage and deafness.

Resistance to antibiotics may be acquired by pathogenic microbes. The resistant microbes transfer genetic material to non-resistant microbes and cause them to become resistant. During antiboitics treatment, non-resistant microbes are destroyed, but resistant types survive and multiply.

To avd the side effect of antibiotics, you’d better not urge your doctor to prescribe antibiotics. Keep in mind that antibiotics are only useful for bacterial infections and have no effect on viruses, so they cannot be used for chicken pox, measles and other viral diseases.
