Amou Haji is an 80-year-old who lives in Southern Iran. According to reports, Amou has not taken a bath since his 20s. The previous record holder was held by Kailash Singh, a 66-year-old Indian man who had not taken a bath in 38 years.
Not to our surprise, when we searched the reason behind Amou Haji's way of life, we found out that he had gone through some emotional setbacks in his youth and from then on decided to live an isolated life.
The nomad believes that "cleanliness brings him sickness." He also smokes a pipe filled with animal feces and says his favorite meal is dead porcupine.

On the bright side, at least he's found a way to save money on toiletries.
