Most colds are not serious, but they can make you feel terrible. Common symptoms include a sore throat, a headache, and a runny nose. If you have a mild illness, rest at home and drink plenty of warm water. Wash your hands often so you don't infect your family. However, if you have a high fever for more than three days, go to a clinic. A physician can check if you have an infection and give you the right medicine. Don't wait too long to see a doctor.

Last spring, my brother injured his knee during a basketball game. He was in so much pain that he couldn't walk. At the hospital, a surgeon told him he needed surgery. The operation went well, but healing took a long time. For three months, he went to physical therapy twice a week. It was hard work, and sometimes he felt like giving up. Our family kept encouraging him. Last week, he finally played basketball again, and we all felt a great sense of relief.
