Emotions are drugs, and drugs are why we care, drugs are why we do what we do. We do everything for the drugs, drugs are both heaven and hell on earth.
My thesis is that no machine can experience what humans can, these drugs are the stuff of heaven. I want them, and they're produced naturally, but shit like nicotine, weed, cocaine, heroine, and LSD produce them is MASS STOCK.
Hatred (norepinephrine) is kinda the result of pain-killing endorphins associated with dopamine production and cortisol, all from epinphrine released when you're stressed. If you're drunk and are harder than an iron-coffin and someone hits you, I don't care if you were falling over sleepy before; all those neurotransmitters will turn you into a hyper-active killing-machine for a few minutes. It feels good to unwind like that, orgasmic even.
Meditation/hypnosis has more potential than drugs to allow a person to operate far more productively than normally humanly possible, you're training your mind to release the right mixture of neurotransmitters to turn you into one resilient son of a *****.
