Video: Chinese man develops taste for iron nails
Long Yunsheng regularly swallows nails up to five centimetres long
Long Yunsheng, a miner from China, has revealed his penchant for eating iron nails.
Washing them down with a cup of water, Mr Long easily swallows several nails with a length of three to five centimetres.
Mr Long, who works for a mining company, said he developed the habit of swallowing nails after he learned it from others about 32 years ago.
Mr Long said: "I was 17 or 18-years-old. I was not sure that the man who could do this was willing to teach me. If a teacher likes you, he teaches you. If not, he refuses teach you."
Despite being able to add glass, ceramics and tiles to his weekly food shop list, Mr Long is said to be in good health.
