How does harm to honour and reason fall under the adage "necessity make forbidden things permissible"?

Islam Q&A write: > Among the basic principles of Islamic sharee’ah, on which the scholars are agreed, is that cases of necessity make forbidden things permissible. > > ... > > Necessity means cases in which a person will be harmed if he does not take the haraam option, in which **the harm will effect the five essentials which are: religion, life, honour, reason and wealth**. They give a collection of examples illustrating under what mitigating circumstances it is permissible to do an ordinarily haram act (e.g., eating haram food to prevent starvation). Religion and life make sense, as does wealth (to a certain extent [e.g., riba is haram]). **Question**: How does harm to honour and reason fall under the adage "necessity make forbidden things permissible"? I'm struggling to imagine a scenario where it would be appropriate to do something ordinarily haram to save one's honour or reason.
