A rather grim book book at first as I'm concerned. Very complex and unclear. Surely bcp information ms must delve into it. J've bought this book after a course of reflexo or we were told some databases psycho morpho (ie recognize the different type of nervous behavior / bilious / blood / lymphatic ...) J had found that genius and wanted to know more, I have not even found the information in this book, however, is simple and c ca sticks very well to reality. (Well at least I looked the diagonal, maybe that is AC but I did not see anything) I think that this book is suitable for passiones studious .. not for me who am just curious
