"Some individuals may perceive their losing fight with gravity as a sharp pain in their back, others as the unflattering contour of their body, others as a constant fatigue, yet others as an unrelentingly threatening environment. Those over 40 may call it old age. And yet all these signals may be pointing to a single problem, so prominent in their own structure, as well as others, that it has been ignored: they are off balance. They are at war with gravity."
