Man able to eat iron nails and glass

 Man eats nails .!

Why did you choose this topic:
I choose this topic because I was always curious about the ways people are able to digest food. to elaborate , everyone has the same organs , but everyone is slightly different from another and probably has a slightly different ways in which they break down food. At first I was thinking about the digestion of sugar and peoples metabolism however this article i found was very astonishing. It makes me rethink. 

2.  How does it relate to what we have learned about the digestive system?:
It relates to the digestive system as it someone actually physically eating something which will go into the digestive tract and being digested. In glass we learned that the the body breaks down food into monomers for digestion this man is able to breakdown iron into monomers a average stomach shouldn't  be able to do that. 



3. My question is what depicts a stronger stomach more hydroelectric acid? if so does he have a special stomach with a stronger lining? was it something he was born with or happened throughout his life.
