Possibly long enough for the person opening it to think twice about the consequences of the action they were about to take? Same concept as putting high barrie

Possibly long enough for the person opening it to think twice about the consequences of the action they were about to take? Same concept as putting high barriers on bridges, or selling paracetamol (acetaminophen) in smaller packs. These changes do nothing to stop someone who is committed to the act, but they provide a small energy barrier which can be enough to defeat the perturbations of a temporarily irrational mind.
