if i was as stupid as a rat, been living in a glass aquarium forever, saw no value or point in life, and was hooked up to a heroin IV against my will, i would probably press the button once or twice to see what would happen. heroin is an addictive drug so yeah id end up doing it more and more

science expirements are supposed to answer questions, and an answer reguarding a rat cannot be juxtaposed to a question reguarding a human.

maybe they should try the expirement on humans?

so, in conclusion... rats tend to have addictive personalities.

(or at least thats all I got out of it...)
