  A simple model is suggested by assuming an effective interaction at the
crossing point of the two curves, the Schwarzschild radius and the Compton wave
length, that is at the Planck length and Planck mass. It is argued that there
would be a physical effect that may be measurable at, say, nucleon mass and
size, while the Schwarzschild radius would remain unaffected for macroscopic
lengths and masses.
