Smell of Sugar Makes Fish Flee in Fear

Scientists in Singapore have discovered that sugar is the key component of a substance produced by injured fish that warns nearby fish of danger. The researchers say their findings could have implications for how fear is generated – and might possibly be controlled – in humans. Photo Credit: icelight via Flickr.

Intriguing. Fish, sugar and humans-a fearful combination? Sounds like fight or flight to me, especially flight and "Get Me Out Of Here!" Some fear is required such as avoiding a situation...running into a grizzly bear - think I will keep my fear in that situation! Other fears such as say fear of flying or open spaces are good fears to get rid of.
Sorry fishes, hope it was not too unpleasant for you, did not look like an enjoyable experience at all. Try that with a Beta! (Joking, people, just joking!)

Thanks. Maybe fish are smarter than humans when it comes to sugar : )

About 8 months ago I eliminated almost all sugar from my diet, and one of the largest benefits has been a much better ability to concentrate. This would seem to go a long way toward explaining that.
