  Starting with the VMD parametrization of the electric and magnetic nucleon
form factors, which are saturated just by the ground state vector-mesons rho,
omega and phi, then aplying the strict OZI rule and the asymptotic behaviour of
form factors as predicted by quark model of hadrons, the famous one parameter
dipole formula is derived. By its comparison with space-like data up to t = -5
GeV^2 the most optimal value of the parameter under consideration is
determined. Finaly, charge and magnetization distributions in proton and
neutron are predicted.
