I want to welcome you to my blog “The Keys to all Mythologies: Science, Medicine and Magic.” I will be posting articles that concern scientific topics of current interest as well as historical accounts of scientific issues. Some of the articles will be relatively long and detailed, such as today’s article about the Opioid Epidemic. Other articles will be short and just designed to introduce a specific concept or a piece of information. I will try to post a new article at least once a month. Please feel free to contact me with your comments or questions!
