There are many benefits to exercise, but not all exercises are good for health. For example, excessive exercise could cause harm to the body, while lack of exercise could easily lead to problems such as obese and cardiovascular diseases. A thousand-year-old tortoise or a ten-thousand-year-old tortoise was a common saying in novels that was usually used to describe a person's longevity or the durability of some items. These sayings were not based on scientific explanations but were based on some traditional concepts or imaginations in myths. They could not completely explain the health of the body, nor could they be used as scientific health standards. In short, exercise has many benefits for physical health, but it needs to be evaluated according to the specific situation. If you want to stay healthy, you should choose moderate exercise and make a reasonable exercise plan according to your physical condition and health.
