Arrogance and Ego in most cases
Jim,
It’s because they haven’t experienced it. My mother had 8 kids. With one of them she told the Nurses she was ready to have the baby. They scoffed! The Doctor had gone home. They were shocked when they had to deliver her baby minutes later. She never dialated like most women. We are all different. Some have horrible pain with bone marrow biopsies and some don’t have any. The body is complex and they are still trying to understand it.
