no such thing as happiness felt without needing to physically alter your mind's mechanisms. its pretty much how all emotions work. chemical reactions are just as physical as you and me and alter how you feel or react or how your mind functions. love turns you dumb, alcohol turns you dumb(on a greater scale), they both create happiness for you, is the happiness caused by both artificial because they alert your mind's mechanisms? of course not. love's happiness isnt any more natural or artificial than alcohol's happiness. mind mechanisms get altered by emotions
