Abstract
A theoretical treatment for the weak decays of heavy-flavour hadrons h as been developed that is genuinely based on QCD. Its methodology as i t applies to total lifetimes and the underlying theoretical issues are sketched. Predictions are compared with present data. One discrepancy emerges: the beauty baryon lifetime appears to be significantly short er than expected. The ramifications of those findings are analyzed in detail.
