One day, a health officer from the local hospital visited Lin Hua's school. Her name was Dr. Lee, and she had studied at a university in northern Europe for a couple of years. She wished to share some important data about personal health with all the students.
"Technology is necessary in our lives today," Dr. Lee said simply. "Data from hospitals can help us reduce many sicknesses." She showed a short movie about how technology is used in Europe to keep people healthy. The movie showed a woman who tracked her own health by herself and kept her personal data private.
Dr. Lee told the students to reduce the amount of oil and salt in their meals. "Indeed, cutting down on oil is one of the best things you can do," she said. A student raised his hand and asked, "How many pounds do people gain if they eat too much, sir?" Dr. Lee answered, "Certainly, every unit of food we eat hits our health directly."
Dr. Lee also talked about babies. "When a baby is born, the hospital uses technology to check every unit of the baby's health," she said. A new mother can also track her baby's data on a private app by herself. This technology helps reduce problems and keeps the baby safe.
After the talk, the students set a date to start their new healthy habits. Lin Hua wished she could go to university someday and become a health officer herself. She knew that the data and ideas she learned today were necessary for a better life.
