Human horse Mohammed Hussein, one of the last rickshaw pullers left on earth, is wiping his haggard face, the sweat pouring forth almost as profusely as the betel nut juice he spits all day long from his ruby-stained lips and gums. He negotiates a fare with a mother and her son, 15 rupees (US30 cents) for a roughly three kilometre slog. The two climb aboard and he takes his place between the rickshaw's shafts, assuming the yoke once more as he has for the past 45 years.
