One thing that stood out was that the "Magnates" (Wealthy landowners) denied the peasants meat primarily because if a child does not get enough protien from birth to about 7 years of age it's brain will not develope properly.
Interesting point mate....This is why it should be a crime to subject a young child to a vegetarian diet!!!!
But back to the book, i think it is written in a fantastic manner and give the POle a lot to be proud of (and a lot to be ashamed of as well) I think the fact that it is not written by a Pole eliminatesd some of the fiercly patriotic bias one finds in other history-based books.
