Yunsheng Long, 49, began swallowing iron nails over three decades ago when he was taught the trick by a circus man.'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 to teach you,' the Chinese miner said.'Luckily, he decided he liked me, so he taught me and I have never looked back. 'I think I have a unique skill and I don't know anyone else in China today who does what I do.'I can get all this stuff inside of me and I remain perfectly healthy. It is just a knack I have.'I like iron nails fresh from the factory the best, with a little trace of oil on them - like a salad dressing! 'Much better than a nasty old rusty nail.'He is often celebrated at fetes and country fairs as the Incredible Human Munching Machine and has claims to have downed 23 lbs of ceramics, nails and glass in one sitting.'I have a throat like iron and a stomach like poured concrete,' he boasted.'A thing has not been made that I cannot get down - and keep down.'(dailymail.co.uk) Bakudaily.az
