Query: opened my eyes

I thought the book was very good and the facts were amazing. The book really opened my eyes to all the horrible, disgusting things that fast food has caused. Eric Schlosser did a great job at finding great facts and really digging up the dirt in the fast food industry. The book spoke about obesity and how fast food has caused a lot of sickness and death and because of this I am sure I won't be eating at the restaurants named in the book ever again.
