In the early 1990s, a quiet man named João quit his job running the human-resources department of an insurance company in Rio de Janeiro and began selling french fries from a street cart. The fries quickly proved popular, in part because they were delicious -- thin and crisp and golden. Even more enticing, João often served them up for free. All you had to do was ask, and he’d scoop some into a box, no charge. What money he did take in, he frequently gave away to children begging in the street or used to buy them sweets. Day after day, he came home to his wife and son without a single real in his pocket.
In his previous life, João -- a chubby man with pointy ears and arched black eyebrows -- had been stern and serious, prone to squirreling money away. But after suffering a health crisis in 1990, at age 49, he wanted to live differently. “I saw death from close up,” he would often say. “Now I want to be in high spirits.” And nothing made him happier than giving. To those who didn’t know him well, he must have seemed like the embodiment of selflessness—the Saint Francis of Rio de Janeiro.
