as we know, health is the most important for us in our daily life.good health enables us to do what we want to do in our career. but bad health gives nothing.
if you don't have good health,you will lose many chances of fulfilling your dream.if you are sick,you couldn't do the job.the boss will fire you.and also sickness will cost you in term of economy.you will pay high bills for your medical treatment.so i suggest that you should not forget the importance of doing excises and sports.
take my case,i play pingpong two hours every morning,i feel energetic for the whole day.you needn't have to worry about going to hospital and seeing a doctor for 5 years.
