What happened that changed Mitch's life and how did it change?This is from chapter 3.

In chapter 3, called "The Student" Mitch tells of his encounter with death.  He writes about his favorite uncle dying at an early age of pancreatic cancer.  This was the uncle that Mitch had wanted to be like when he grew up.  This was the uncle that had taught him to drive, to play the music he loved so much, and taught him about girls.  He spent the last year of his uncle's life living in an apartment below his uncle and his family.  After his uncle died Mitch writes that he felt that time was suddenly precious and he couldn't get enough done fast enough.  He enrolled in school and got his Master's degree in Journalism.  His career took off and he worked hard and long to use the time before time could use him.
