[Q]: This is not a new book;perhaps that's why it is so useful.There is no gobblygook, no arcane economic theories with fancy lables.What there are in this book are many examples of - - if the government takes this action to make this or that happen, the unintended consequences have proven to be and will probably be again something quite different, and usually not positive.Sound experiential economics in my view, clearly written; and a tremendous help to understanding what will probably happen if the nation takes on more debt, subsidizes this or that interest, taxes one interest at the expense of another, etc.I liked it; I could read and understand it.
[A]: Positive


[Q]: I've heard it said that this is Kerouac's greatest novel. I still say that honor is held by On the Road, but this book is just as good. And it is his most spiritual novel. Kerouac combines his talent at writing with his philosophy of life and what you have is a powerful tool to enlightenment. This book should be read on at least two levels, as a work of great literature and as a theological tool. I can't recommend it enough.
[A]: Positive

I tried to wear other side, after few hours, I got deep burned both on the right and left belly, the skin was torned, swell, bleeding, lot of cross cut on the skin, itched for a week until now.
