  Assuming so called global duality we argue that it is very likely that local
duality needed to obtain results for the hadronic width of heavy meson decays
within the $1/m_Q$ expansion holds. Hence, if the discrepancy between
experiment and the theory concerning charm counting, the semileptonic branching
fraction and the lifetimes of $b$ hadrons persist, it may be taken as a hint at
some qualitatively new effect in (nonperturbative) QCD or even as a new
physics.
