27、I think healthy habits are important for us．As we know, we must have enough health food. it’s necessary to have breakfast on time．When we have meals，we should eat all kinds of food like fish．eggs，and meat．Remember to eat a lot of fruit and vegetables．Don’t forget to wash your hands before meals．Staying is bad for your health．so you’d better go to bed early and get up early．Of course．It's good for us to take more exercise such as swimming, running and playing basketball．It will keep us active and strong．
