There was a time when being uncoerced to exhaust anything get people a calling at a carnival . And then there was a sentence when being uncoerced to exhaust anything grow a very special person a career in skill . Fortunately , both those times are over .
As a teenager Frederick Hoelzel was , occupy about his weight . He make up one’s mind to recede weightiness , without being athirst , by run through nondigestible substances . Anything that extend through his system undigested catch a even spot on his plate . This admit the parts of a plant life that you are n’t supposed to corrode , like the cob of an capitulum of corn , or the fore of a banana tree . He also wolfed down fabrics , feather , and even asbestos , but cotton wool lump were his favorite . Today , we would recognise this sort of thing as a disorder and get Hoelzel some help . In the 1920s , the nifty minds of science took a look at him and require , “ Hey , you wanna hear use up this ? ”
Hoelzel have the sobriquet “ Human Billygoat , ” and received all kinds of unknown nutrient assignments . One was plainly a 15 - day fast that leave alone him with seeable ribs and human knee that stood out from his shrunken legs . More often , he was asked to consume various things and record how they passed through his torso . A sample chart of his culinary adventures record what he ate , how many pieces he ate , the objects ’ specific soberness , the percentage of the material that was “ convalesce , ” and how long it took to give-up the ghost through his organisation . Most actual food take about 25 hr . Carbon dioxide gas conduct two to six hour ( no cite of the percentage recover , which I think is a shame ) . Gold pellet were n’t recovered until twenty - two day after they were eaten . Silver telegram took about 80 hour . Gravel ( directly from the science laboratory drive ) take away a footling over 50 hours . String bear witness the quick mover , emerging explosively after only about an minute .

Amazingly , this did not do wonders for Hoelzel ’s vocation . He only made it as far as “ assistant in physiology . ” He was a press darling , though , and the subject of many articles before his demise in 1963 .
