At what age do we develop courage? Hard to say. For some it may never be necessary. Things just happen and you're content to go with the flow, taking the road of least resistance and having a comfortable journey through life. Others, though, hold beliefs they know to be right and true. They will defend these, often with their life. They don't have to be big earth shattering truths, just knowing what's right and wrong and deciding to speak up about it when something is wrong.
I don't believe courage arrives at a certain age. It is more often nurtured in the home and can appear at anytime when fearless action is called for.
I think Pakistani schoolgirl Malala Yousafzai is incredibly courageous. She is the daughter of a school principal and was deliberately shot in the head three weeks ago in her country by the local Taleban. Why? Because she believes girls have a right to be educated in Pakistan and said so. She started early being courageous and finding her voice. She wrote a popular blog for the BBC for two years detailing what life was like in her province living under the influence of the Taleban, the hardline Islamists who terrorise her home area. Pakistan was not always a country that saw education for girls and women as bad. In fact free and compulsory education is a right of all Pakistani children in their constitution.
It is only since the Taleban has gained influence in certain provinces that changes are being imposed on the roles of girls and women in Pakistani society.
It is hard to believe that any modern country would consider it wrong and pointless for girls to receive an education. If a government or a controlling group feels so strongly that girls shouldn't receive an education, why not allow the girls themselves to decide. But with pressure being exerted daily throughout Pakistan by the Taleban, that's hardly likely to happen. When you allow an unelected group to call the shots, this is a form of bullying.
