The Conditioning of Emotions

What determines our emotions is our "Conditioning", (different for all individuals), to respond to our environment; This conditioning is active throughout our life by our experiences, our education, our environment (everything that surrounds us and that we can apprehend with our senses, hearing, smell, touch, sight ...) and evidently a bit of genetic as well. All these factors will forge our body responses through chemical reactions and through neurotransmitters (I should find some interest in physiology to see) who therefore react to certain things becoming "triggers"; some will have fear of the dark, others will like girls with hair slide, others will find interest in cars or video games, others will enjoy the rain and hate the sun .... etc
