Thorax Intensive Care Unit

It is a bit strange, that you are sometimes interested in reading about something you are very familiar with and know a lot about. Tonight, Paula said she was going to read about the thorax intensive care unit. This is the unit at the hospital where she is working. Thus, she knows about it. Still, she reads about it. I guess it is like when I read anout dog shows, despite being a dog show professional, or read about dog behaviour, despite being a dog myself. It is odd, I admit that. I guess it is common, nevertheless.
