Melissa Anderson is an 18-year-old high school senior. She is a good student and plays forward on her undefeated varsity soccer team. She is playing in her last state tournament on Saturday. In the past week, she has not felt like practicing (her body aches too much) or studying. When her friends invite her to go shopping – something she would normally be excited about – she declines and stays home to sleep.
Melissa likes to actively manage her health. When she wakes up, she checks her personal health record (PHR) on her smartphone and sees she has lost six pounds in the last two weeks.
