alright for addiction. im interested in how addiction works. like do people get addicted to the act of doing, say smoking. or become so accustomed to the effect of the drug. such as relaxation. that you need a smoke for the effect. or does the chemical change your brain chemistry so that you essentially require a drug to keep going. as for phobias. im wondering with those cat scan graphs and stuff. is it possible to actually proved empirically what emotion or feeling a person is going through? Like ive brought this up before. http://phrontistery.info/phobias.html" Essentially. Like neurologically. could you tell why these are. and if they are true fear?
