An Iranian man nicknamed “the world’s dirtiest man” was a recluse who refused to bathe for 60 years. Kailash “Kalau” Singh, from a village outside the holy city of Varanasi, would reject water in favour of what he called a “fire bath”. “Every evening he lights a bonfire, smokes marijuana and stands on a leg praying to Lord Shiva,” local media said. He reportedly enjoyed eating roadkill and smoking pipes of animal poop, and believed being “clean” would make him sick. And maybe he was right - when neighbours finally convinced him to wash up, he died just a few months later. Then again, he was 94.
