There is an interesting phenomenon here in the Philippines that is noteworthy. Men will pay women to be with them, and somehow the feel empowered or invigorated as if they are handsome.
This is a mind twisting feature that happens to the men who live in Angeles City or the Philippines. They are told they are handsome so many times, they somehow ignore the mirror and believe the voices talking to them.
