  A new qualitative stringlike picture for mesons is proposed which leads to a
simple and intuitively clear generalization of linear radial Regge trajectories
to the case of massive quarks. The obtained universal relation is successfully
tested in the sector of unflavored vector mesons, where many radial excitations
are known. Some new predictions are given. Our results suggest that the quark
masses can be easily estimated from the spectra of radially excited mesons.
