Ricky - can I ask if when you describe your mother-in-law as "dynamic", needing a dynamic remedy (higher potency) do you mean a dynamic personality, outwardly or a dynamic "vital force"? Can a being have a dynamic behavior but have low vital force? I think of animals (of course) that are young and seemingly "full of life" but show signs of serious chronic dis-ease. Would they still be candidates for higher potencies or would it be wiser to begin with lower potencies considering their constitutions must actually be compromised (lowered vital force) regardless of their apparent hardiness? (As an aside-I think chronic dis-ease is easier to see in animals than in humans. There are specific visible symptoms that exist before they actually become "sick".)
