Medicine & TechnologyJK Rowling shared a video on how to do proper breathing techniques for those afflicted with COVID-19. She claims to have been stricken with the virus, and the breathing techniques coached her back into full recovery. The video is of Dr. Sarfaraz Munshi, who works at Queen's Hospital in London. Since the disease targets the respiratory system, Munshi cautioned patients to stop lying on their back, as it restricts breathing.
