heal.abstract	We provide compelling evidence that a previously introduced model ofnon-perturbative 2d Lorentzian quantum gravity exhibits (two-dimensional)flat-space behaviour when coupled to Ising spins. The evidence comes from botha high-temperature expansion and from Monte Carlo simulations of the combinedgravity-matter system. This weak-coupling behaviour lends further support tothe conclusion that the Lorentzian model is a genuine alternative to	en
