Peter has recently begun to have great headaches that he could no longer withstand. Therefore, he was forced to go to the doctor for a check-up and to find out what are the reasons of Peter's troubles. After a quick check-up, it was clear. It looks like strong concussion and inflammation in one. Well that's not good news. Fortunately, the clinic has excellent doctors who will certainly be able to help him. So put your white cloak on and go! This will not be a routine operation, there's a lot of work to do! Save Peter's life before it's too late. Have fun.
