The long {ital B} lifetime is related to the heaviness of the top quark by a particular mass-mixing ansatz. The {ital u}-type quark mass matrix is of the Fritzsch form, while for the {ital d} type it is diagonal except in the {ital d}-{ital s} plane, which generates the Cabibbo rotation. We predict {ital m}{sub {ital t}}{approx gt}200 GeV from {ital V}{sub {ital cb}}{approx lt}0.06. One gets maximal {ital CP} violation,'' and the relations {vert bar}{ital V}{sub {ital ub}}/{ital V}{sub {ital cb}}{vert bar}={radical}m{sub u}/m{sub c}, {vert bar}{ital V}{sub {ital td}}/{ital V}{sub {ital cb}}{vert bar}={radical}m{sub d}/m{sub s}, and {vert bar}{ital V}{sub {ital ts}}{vert bar}={vert bar}{ital V{sub cb}}{vert bar} are close to exact. An interesting Wolfenstein pattern emerges. We discuss the viability and implications of having such a heavy top quark (such as lower {ital M}{sub {ital Z}}), and the possibility of a vanishing {ital V}{sub {ital ub}} and its impact on {ital CP} violation.
