Guru Kailash Singh, 65, could be the world’s smelliest man after refusing to wash for 37 years. He lives with his wife and seven daughters and has gone decades without taking a bath, shower or using a bar of soap. Kailash, from Chatav village, near the holy city of Varanasi, in central India, believes that the gods will be pleased with his devotion to smelliness and smell and eventually bestow him with a son. He also sports six feet dreadlocks and an uncut messy beard.
