Living for others key to happiness for Japanese winner of 'Asia’s Nobel'

Ophthalmologist Hattori Tadashi quit his high-paying job in Japan two decades ago to give impoverished people in Vietnam access to eye care. Since then, he and his team have restored the vision of more than 20,000 people free of charge. Now he has been named one of four recipients of this year's Ramon Magsaysay Award -- often called "Asia's Nobel Prize" -- for his humanitarian work.
