Query: Fat Free Yoga is a Good Video!

"Fat Free Yoga" by Ana Brett and Ravi Singh works reasonably wellto reduce "toxic wastes" in the endocrine glands andto reduce and control nerve-pains without causing much muscle-pains.It is worth doing the exercises presented in this nice video!------------------------------------------------------------------------5th year with "Fat Free Yoga" since beginning of 2009!Still very effective.A Suggestion for "Real Experimentation in Powers of Yoga"specially for Ana Brett and Ravi Singh!( If Ana Brett did her "Yoga Poses" decently dressed, she would be even more effective.And their Videos would sell even more, bringing more business to them.)I am going to believe that that is so, no matter what else.
