Linda is my good friend.We always study together.She's a smart and friendly person,and she is very healthy.
She usually exercise three times a week.So she hardly ever have illness.She eats junk food once a week,because she knows eating too much junk food is bad for her teeth.She goes to sleep early every day,because having enough sleep is very important for every one.
So she keeps healthy very well.
