[EX Q]: 'The most dangerous man alive'? Doubtful...more like an individual who proves how influential environment is on forming of human character. If you read this book and don't in some small way sympathize with the human being that is Charles Manson then you're less human than the 'monster' he is purported to be. Inevitably there is bias and self indulgent perspectives conveyed here; the writing is relatively average as well though it flows smoothly & does compel one to turn the page, even with droopy eyelids. At least it is an answer to the best seller written by the man who was most instrumental in putting Manson behind bars; at most it's as close to a confession the literary world will probably ever see from Mr. Manson.
[EX A]: Positive

[EX Q]: it just gets better ever time do you know if there will be a 4th one, i loved the action but come on does it have to be a super model evertime that is the girl?
[EX A]: Positive

[EX Q]: This DVD is a must have for anyone who is going through childbirth...your birthing class may not explain things with this much clarity and detail (I know my didn't). I learned a lot about breathing, and controlling your breath, and although I am not planning on using drugs through labor, I thought her section on medical interventions very useful.
[EX A]:
Positive
