Query: Stretched Horizon for Non-Supersymmetric Black Holes   We review the idea of stretched horizon for extremal black holes in
supersymmetric string theories, and we compute it for non-supersymmetric black
holes in four dimensions. Only for small masses of the order of the Veneziano
wavelength is the stretched horizon bigger than the event horizon.
