enismirdalRats can be trained to push levers for a sugary food reward.
However, when those rats are then fed the sugary food pellets, but immediately afterwards injected with lithium chloride, which makes them sick, they show aversive behaviour, i.e. they lose interest in the pellets and stop pressing the lever for them. (This is logical as it means they won't ingest a poisonous substance twice in the wild). The same phenomenon is observed in students who have once made themselves hopelessly drunk and sick on gin; they then show aversive behaviour and refuse to drink gin.
However, evidently I do not have that logical reaction. Despite last night's sucrose excesses, I am displaying no aversive behaviour; I have bought myself a whole pack of Jaffa Cakes with the intention of comfort-eating all evening.
Conclusion: Eni is dumber than a rat :)
