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-Nordstrø{m} black hole in $D=4$ can be built from different sets of constituents such that it has zero, positive or negative binding energy.Latex, 13 pages, references addedHigh Energy Physics - Theorytext
