Abstract
The issue of gauge unification in the (non-supersymmetric) Standard Model is reinvestigated. It is found that with just an additional fourth generation of quarks and leptons, gauge couplings converge to a common point GeV ( years) provided the Higgs boson has a mass of at least 210 GeV. The presence of ultraviolet fixed points for the Yukawa and Higgs quartic couplings is found to be the origin of such unification.
