Query: Changed my LIFE!

I suffered with Rheumatoid Arthritis for 8 years. I was depressed, and prone to panic attacks from so much pain, for so long. Three months on my blood type O diet, and I was pain free! This man gave me the key to be well, and free of the mis-information out there regarding "One Size Fits All", diets. You can take drugs to suppress your symptoms, but you will never be well on them as "Eating Right for your Type" can provide. BUY IT!
