A molecule has everything to do with a feeling. Feelings are chemical reactions, and chemical reaction are caused by molecules. In fact, you should receive a molecule as your personal Lord and Savior.

Because they release when you feel good. So from infancy you associate the feeling that you get when endorphins are released with feeling good.

Molecules as you put it of endorphins have to do with feeling because they supress pain and they heighten affect. If you are asking what is consciousness that is an entirely different and far harder question to answer.

On a molecular level endorphins resemble opiate molecules, they fill the same receptors.

They just don't make you itch and vomit.

cause they modify the activity of the post-synaptic neuron and hence suppress negative emotions and pain

endorphines bind at the same receptors as opium, its basically a drug. thats why molecules have an effect on your feelings.

Thats kinda like asking what a hiccup is really.

They feel good because they are designed to produce that reaction in humans.

Yes

<edit> Sorry, you said "why"?

I think because they have a similar effect on your brain as an opiate does.

For the same reason orgasms do. Nature designed us that way.

Cause they're better than outdorphins?
