This that you mention is very important. When I was a child my stepfather worked with paraffin, I remember getting dizzy when it was heated. Fortunately, I didn't have to stay in that environment. As an adult I have been concerned about health, I even studied traditional Chinese medicine at the Neijing Caracas Foundation, I finished the acupuncture course two years ago, but I always read about natural medicine. I really like your posts.
