 No, you're right. It requires additional training outside one's normal core training to be a doctor. There's no question about it. It's a subspecialty, but, of course, going through endocrinology training and physiology training, you get the basics of it, but you get out in the world as a licensed doctor, and somebody comes in and says, oh, man, I'm sweating to death at night. I'm gaining weight. I have dry vaginal problems.
