Bonus: 6. Stay in Shape
6．保持良好状态
You only get one body. Once it's been ruined there isn't much you can do about it. Exercise to keep the rust off. Avoid excessive consumption of damaging substances and unhealthy foods. It may feel like terrible self denial at the time but enjoying good health in your later years is worth the sacrifice.
生命只有一次。一旦身体出了什么问题，就再无法挽回。多做运动会让身体更加健康。尽量避免有损身体的过量运动和危害健康的食物。也许你会有反抗情绪，但为了以后的健康生活，这种牺牲绝对是值得的。
