I grew up in a rubber plantation on the outskirts of a small town in Malaysia in the 70s. What the locals might call 'ulu' in our dialect. Forget a lack of healthcare services - going without fresh water or electricity for weeks at a time was the norm. I have been treated by a witch doctor. When I say alternative, I do not mean homeopaths or naturopaths. I mean witch doctor. The kind that cast spells and exorcist spirits from you. Having survived the experience, and bearing the obligatory keloidal scarring that come with well performed rituals, I am here to once again speak to you about evidence based medicine.
