Game changers and heart failure

Bruno Giussani takes a look back at a wide range of ideas and some fascinating people of the past year. The dozens of people he lists are all important, but the media and social entrepreneurs in particular I admire for their use of existing tools to make a difference in the lives of others. Despite my strong faith in the power of ideas, so many problems in the world can be traced to a simple idea, heart failure, and proportionally, to a failure of my heart. So to Sasa Vucinic and Iqbal Quadir and Carl Honoré, game changers all, bravo.
