Why Emily is healthy

Emily, my classmate, is healthy. There are some factors why she is healthy. First of all, she has swum for nine years. Her major is swimming. So, she can swim very well until now. The next reason is that she doesn't smoking. Also she doesn't like alcholic beverages. When her condition is good, she drinks a little alchol. Third, she has regular habit(use plural). She gets up early every morning. Because she has to go to school on time. And she eats meal same time everyday. Also she goes to bed early. Finally(comma) her personality is very good. She is optimistic and she has simple mind. I want^ be like her.
