Yes, you can almost get your medical degree on YouTube; however, tis not quite as detailed as the following. My favorite 3 medical textbooks of the 12 that I own, are as follows:
"A Guide to Physical Examination and History Taking", by Barbara Bates, M.D.
Next, I needed "Stedman's Medical Dictionary, illustrated in Color", to help me with a greater understanding of the information that DR. Bates' shared..
And, lastly, I found that "Fundamentals of Nursing; The Art and Science of Nursing Care" was an equally necessary part of my limited medical education, to provide me with some of the basic tools, necessary to be a fully accredited play.doc.
Tis my thought that you need some qualified medical textbooks if you are going to play; otherwise, you may well be playing in the dark, and that could be unsafe and/or harmful.
Now, go out and make it a gr8 day!
