well, I'm a freshman and i was required to read and do multiple projects with this book; as a person who is pretty much addicted to salt and puts it on everything , I thought it would be interesting. HOWEVER..... I even had my PhD sister read this book and we both fell asleep out of boredom , it was a daily chore. I would sooner kill myself than reread this book, the only pro was there is a index in the back for me to only have to review as much as required...BEWARE!!! IT SUCKS!
