Powerful men,
They tend to be quite quiet actually.
Men who are wealthy, healthy, intelligent and full of testosterone, they do not want to be known to the world so they do their thing from the shadows.
They do not want to expose their power because in doing so, well everyone would know!
If they show their power by behaving brashly, over-confidently, egotistically then the chances are that someone who is in need of power will notice, which is not good.
