Most Idols are men and they work/worked with entertainment.

1. Yes,because the entertainment is a very big space with both sexes involved and surprising me to know that some men appear more even among women.
2. Yes, the number of men was much higher than the number of women mentioned.I found it very unteresting to know because many of the interviewees were women.But I don't know why that happened.
3. Because it is a well known work area and spokn by people.
