  We point out that there is a parameter region in supersymmetry with heavy
scalars and higgsinos, in which the heavier of bino and wino becomes long-lived
as a consequence of the heavy higgsinos. In this region these electroweak
gaugino sectors are secluded from each other with very small mixings that are
inversely proportional to the higgsino mass. We revisit the bino and bino
decays and provide simple formulae for the partial decay rates and the
lifetimes in the limit of heavy higgsinos. We discuss the collider signatures
of the long-lived binos and winos in this scenario.
