Health is the guarantee of one＇s happiness. Without a healthy body, one cannot do what he wants to, not to mention accomplishing his goals in life.
One can keep fit in three ways. First, he is to pay attention to hygiene. Stay away from viruses, which means one should wash hands, take baths frequently, eat and drink properly. Stay away from bad life habits, such as smoking and overworking, which severely damage the body organs. Secondly, one is to exercise regularly. He may go jogging, swimming, bicycling, playing basketball and so on. Exercises will improve one＇s ability to resist diseases. And last but not least, he should be optimistic, fearing no difficulties and obstacles, and always being in high spirits.
Only in good health as well as in high spirits can we greet the future, which is full of competition and challenges, and strive to achieve our ambitions energetically.
