As we all know， keeping healthy is important for every one of us. \tWe can’t be offered good jobs in the future if we are not strong enough.\t So， how can we keep fit? In my opinion， we should try our best to do \tthe following:\tFirst， I think you’d better take exercise every day. \tIt is considered that people who do sports every day have more healthy \thearts than those who don’t. However， it’s best to exercise regularly. \tHalf an hour a day is enough. Spending too much or too little time on it\t is not a good idea.
