The episode wit Dr. Li, author of 'Eat to Beat Disease. Aired December 6th, 2020. Rachel was highly irritating to me. She kept walking over Dr. Li's words, interrupting him everytime he tried to speak and demonstrate very interesting topics about DNA and food. She was so obnoxious and rude. I actually thought she was on something behaving like she was intoxicated. I kept waiting for her to calm down and it didnt happen. I didnt hear hardly anything he had to offer the audience.
