Still on the topic of hookworms. My mother said that she never gave any of her children boiled water when we were growing up; just water straight from the tap. According to her, that is one of the reasons we have really strong immune system. None of us has ever had typhoid, for instance. This would seem to support the hookworm guy’s claim. You can listen to the edition of This American Life here. In case you are wondering, I grew up in a small, Nigerian town.
