Recently, had someone argue with me about the chemical changes in our body and how they make us feel. i stated to them that eighty hd is a environmental disease and they argued with me on. and this episode, I make it clear and apparent as to why I believe that the chemical changes in our brain can be affected by environment. please take an opportunity to see my scholarly approach at something so trivial, that'll make you wonder what you've been told is true or a lie
