This was knowledgable. I've been trying to research for a video like yours that teaches the stuff in this video. That description at 1:12 is my fav. Your video totally reminds me of the videos from Dr. Ethan! Dr's demonstrations are really insightful and I really learned a lot for my school. He is an insightful medical student on KZbin and he talks about health! I recommend you check out his YT out and give the Doctor a subscribe! 👉 #DrEthanEducation
