In the aftermath of a building collapse in East Delhi, India, that left some dead and more suffering, Omkar Nath Sharma felt helpless. Before his very eyes, people in pain, some dying, needed medicine but had no money. And the local hospital could not help. Then it struck him: maybe people had medicine in their homes that they no longer needed. Though he was 80 years old, he could walk, he could talk, he could collect medicine for the needy. So he started calling out to people in their homes from the street, "Do you have any medicines that are not of use to you?" And he collected castoffs to give to those who needed the medicine. Then, the movement grew. This short video tells the story of Medicine Baba, whose successful operation with humble beginnings has saved countless lives.
