What does it mean to be a real man in today's world ?
In my opinion to be a real man in 21th century is associated with huge liability . In view of men physical predisposition they have responsibility to contorol their strenght and use it to do beneficial things. Men also have to protectet and respect women, care about their families. So nowadays to be a real man means to suffer the responsibility and consequences of their actions , and take'em on chest "like a man".
