Abstract
We present a stellar evolution model sequence of the past and future evolution of the post-AGB born again star Sakurai's object (V4334 Sgr). In order to match the short evolutionary time scale we have to assume that the convective ingestion of hydrogen-rich envelope material into the He-flash convection zone proceeds slower than predicted by the mixing length theory. For the future we predict a swift second evolution through the central star region before a second born-again evolution occurs.
