Q: If you are not in really good shape this is a great product to get ready for P90X. It does get kind of boring because you are doing the same workouts every other day, but they do work. It is only about 30 mins but it is amazing how well it works.

A: Positive

Q: This book was in my library's Genealogy section, and you're not allowed to take Genealogy books out of the library. But I liked it enough to sit in the library and read it, in two sittings.This a quick read, because it has loads of pictures: photos of the ghetto and its inhabitants, and also pictures of artifacts such as ration cards, work certificates, yellow stars, etc. It's more like a museum exhibit than a simple book. Because of the format I think young people would be able to get something out of the book too, although it is clearly written for adults. Certainly it probably has the most information on the Kovno/Kaunas ghetto all in one place.Both researchers and the ordinary person interested in the Holocaust would enjoy this.Bonus: pages from the diary of Ilya Gerber are printed in this book; you can read extracts from the diary in Alexandra Zapruder'sSalvaged Pages: Young Writers' Diaries of the Holocaust.

A:
Positive
