This can happen anytime, and could since the times human life became more complicated than hunting and gathering and living in caves.

Negavive emotions (and physical pain) may be a warning, but I strongly wish I'd have more control over them. It reminds me of a typical scene from a naval or sci-fi movie, when something happens and there's an alarm siren blaring. The captain comes to bridge and asks some crewman to shut off the alarm sound. Because such a warning is useful until it's heard and understood, and then it's only seriously distracting. Much like negative emotions and physical pain.
