Night .
During extreme times a person can survive. One could look at NIGHT by Elie Wiesel. We can see many different people in the book fighting to survive. By examining Elie and his father one can see details of people fighting to survive. The book NIGHT shows that a person can survive extreme conditions. For example Elie ran 42 miles in one night without stopping. This shows one can push themselves just with the thought of living, even most athletes would have trouble running this far. This also shows that something horrible could make someone stronger.
At another time in the book Elie watched his father being beaten. This shows that even though a loved one is being hurt Elie still thinks about survival, because he knows that if he intervened he would have been hurt or even worse killed. This also shows that one can drop into a robot like state to stop his emotions, because if he felt sad or cried he might have been harmed. For example Elies father was a 50-year-old man and he survived for over 3 years in the concentration camps. This shows that even an older person can fight to survive now days being 50 and still doing things isn't that big a thing but back then there had not been that many medical advancements. This also shows that someone can push themselves beyond normal limits of human strength. So it all come down to thier strengh of there mind and will.
At another time Elies father was beaten and he didn't fight back. This shows that Elies father was strong enough to be beaten by ametal bar was striking him and a normal person wouldn't have been able to put up with that but since Elies father was thinking about surviving so he was stronger. This also shows that even though Elies father wanted to fight back (there's no actual evidence of this but who wouldn't want to fight back?) He didn't because he knew that he would have been killed if he fought back so by thinking about survival he knew he had to be beaten.
