Supersymmetric p-branes that carry a single electric or magnetic charge and preserve 1/2 of the supersymmetry have been interpreted as the constituents from which all supersymmetric p-branes can be constructed as bound states, albeit with zero binding energy. Here we extend the discussion to non-supersymmetric p-branes, and argue that they also can be interpreted as bound states of the same basic supersymmetric constituents. In general, the binding energy is non-zero, and can be either positive or negative depending on the specific choice of constituents. In particular, we find that the a=0 Reissner-Nordstrøm black hole in D=4 can be built from different sets of constituents such that it has zero, positive or negative binding energy.
