（单词翻译）
People who sit down a lot must exercise for one hour a day to live longer. Sitting down a lot makes our life shorter. It is like smoking or being overweight. Sitting for eight hours increases the risk of dying1 early by 60 per cent. But, one hour's exercise each day means we may not die early, even if we sit down all day.
Researchers hope this news will get people to exercise more. Watching TV all day is also unhealthy because we eat snacks. No exercise increases the risk of heart
disease2. People should get out of their seat more. They should take breaks every hour, or walk upstairs. We need to add more physical activity into our daily life.
