A school dropout from a poor family in southern India has revolutionised menstrual health for rural women in developing countries by inventing a simple machine they can use to make cheap sanitary pads.
His wife left him, people in his village scorned him, and then his own mother left him. Can you imagine the sheer grit and determination this dude must have had in order to achieve such a feat in, of all places, India (where female menstruation is still seen as a taboo topic)? There really are people who are just born to be an entrepreneur.
