Mario Antonio Duarte: Mario Antonio is 61 years old, and unmarried. 'I've been an odd job man all my life. I have helped unload lorries, cleaned them, looked after cars. In good months, I make 900 reais, enough for a shabby room and a bit of food. Does that worry me? No. I don't drink, don't smoke, respect all living things and my transistor radio is my best friend.' Sao Paulo has also treated him well, Mario says. 'I worship this city. I was born here. My mum's father was German, my dad's father Portuguese.'
