  We elucidate the physics underlying ``anomaly mediation'', giving several
alternative derivations of the formulas for gaugino and scalar masses. We
stress that this phenomenon is of a type familiar in field theory, and does not
represent an anomaly, nor does it depend on supersymmetry breaking and its
mediation. Analogous phenomena are common in QFT and this particular phenomenon
occurs also in supersymmetric theories without gravity.
