Force creates counter force. That's a basic law of human nature. I'll repeat, there is no force without the counter force. Also, the terminology is arbitrary.

Force creates counter force. That's a basic law of human nature. I'll repeat, there is no force without the counter force. Also, the terminology is arbitrary. Water can surely create endorphin when you are really thirsty. Toxins are problematic, but even water is toxic in high quantities. What's really toxic is dogmatism ... and narcotics that numb senses, which is the opposite of stimulation if you think about it. Only, it's not black and white like that, if the body is stimulated to feel less. Anyhow it's pretty simple to see which side f the equation is the extreme negative. Fiding the middle is difficult and hence dangerous.
