[The Grand Nudger]

If you would have paid attention to the article you would have understood that certain reactions only happen under certain circumstances like when the grass is cut a certain smell is released.

An instance of damage to containing tissue.  

The release of that particular smell is not happening under other different circumstances.

You could tear the grass or chew on it and the voc is released.  Though, for most of us, you've have to hit a substantial patch of grass. Mowing the lawn is pronounced for the massive amount of damage a mower inflicts over a wide area.

This clearly show that your point in which the smell is released through over saturation is a load of BS.  

You don't have to cut mint to smell it..though it does help to pronounce the effect if you crush it, causing further damage to already saturated tissue.

Aromatics are the worst example of what you're trying to drive at. There are much better ones. Like plants that release predator specific vocs that call in help from predators of the predators. We know how they do that, too, though, and the answer isn;t "brain" or "consciousness"

OFC, I can;t prove that the cricket didn't kick dogs in a previous life...so maybe it;s happening by karma, nothing to do with the underlying mechanics of the plant tissue... because jimminy deserved it. Did you think of that?
