As a Type B, you carry the genetic potential for great malleability and the ability to thrive in changeable conditions. Unlike blood types A and O, which are at opposite ends of every spectrum, your position is fluid, rather than stationary, with the ability to move in either direction along the continuum. It's easy to see how this flexibility served the interests of early Type B's who needed to balance the twin forces of the animal and vegetable kingdoms. At the same time, it can be extremely challenging to balance two poles and Type B's tend to be highly sensitive to the effects of slipping out of balance.
