    Running is becoming popular these days. Many of us run for health. Doctors say many health problems come from these bad habits：eating and drinking too much, smoking and not taking enough exercise. Doctors tell us, “Eat and drink less, don’t smoke, and exercise more.”

Running is a good form of exercise because it helps build a strong heart. It also helps most people lose weight. One 68-year-old woman runs three times a week. “I love to eat,” she says. She runs to lose weight.
