我爷爷今年六十岁了。
My grandfather is sixty years old this year.
他每天都去。
Every morning he goes running in the park.
以后，他觉得很好。
After running, he feels his body is in great shape.
爷爷说：可以让人不。
Grandfather says: running can keep people from getting sick easily.
，我们要健康。
So, we should pay attention to our physical health.
每天运动，一定好。
Exercise every day, and the body will surely be healthy.
