Are we all just drug addicts?

[Angrboda]

There will be something about attending Church that generates something postive in the brain. This is most likely due to childhood nuturing.

No nurturing required. Religious behaviors gravitate to natural brain stimulants. Singing, chanting, dancing, waving your hands in the air, touching other people — these all have powerful and totally natural effects on the brain. It's probably a simple evolution of behavior; the more natural stimulation an act has, the more likely it will be incorporated into ritual. And then there's the drugs, ayahuasca, peyote, the drug used in the Eleusinian mystery cults, soma — many religious rituals involve powerful psychoactive substances.

There are any number of ordinary behaviors with powerful mind altering properties. Religion just cobbles them together to create a brain stew.

What other reason is there to listen to something incomprehensible spoken in a dead language? It's all just twiddling the knobs on the brain.
