text: Mia: My back is killing me again
  Andy: It's because you sit all day at work
  Mia: what else should I do at the office? :D
  Andy: every hour you should go for a short walk
  Mia: forget it, I'm swamped
  Andy: everybody says so and then they have back pains - jeez I wonder if that's connected
  Mia: Maybe I will go get a massage or sth
target: Mia has back pain. She's too busy at the office to go for a short walk. She considers having a massage.
