Shameless pseudoscientific garbage from someone in trouble with the FTC. To paraphrase Jeff Foxworthy, "You might be an idiot if you spend good money on this book." As someone with a Ph.D. in Plant Science, it saddens me that real trees were used to manufacture this thing. If you have a need to be paranoid about something, direct it towards the IRS, the new world order, or Roswell aliens. Save your money and your health and pass this one up. If ever there was a good argument for book burning this would be it. You have to give it one star or the system won't accept the review -too bad, it should get a minus 5 stars IMHO. I do get good use out of it. I wave it around in front of my Basic Biology class every Fall semester as an example of the very real dangers associated with poor science literacy.
