We live in toxic times. Never before in recorded history have human beings been packed so closely together, under such toxic and stressful conditions, as in our cities today. Never before have we exposed our planet and our bodies to so many different kinds, and increasing quantities of toxins (poisons). This includes chemicals, heavy metals, toxic fumes, radiation, and other poisons in our air, food, and water. No one knows the full consequences of all these different toxins building up and interacting inside human bodies. But we can see some of the effects in bodies around us, or by looking in a mirror.
