text: The topic you need advice on may have also happened to other people. People have personal experience in some of the same topics, and that's why it's good to seek multiple opinions. Tragic events happen to people everyday, and that's a factor in what can affect people's opinions. For example, women who have had a baby may have a different opinion than a childless woman. People are also very educated. If you needed advice on a medical topic, it would be best to go see someone who has a degree and is experienced in the field. If you were to go to your friend who self-treated them self, he or she may tell you something completely different than an experienced person in the medical field may tell you.
