There is nothing wrong with the knowledge or content. The presenter simply has a poor venue which amplifies his distracting heavy breathing and lip smacking(in all of his videos). It is the exact same thing as word whiskers such as uh/um/er that sort of nonsense. It distracts from the content. That isn't whiny, its a legitimate criticisms. I want to watch the video for the content, but it the equivalent of watching people shovel food in their mouths. And thanks for making me have to clarify that. Please explain how his "type of medical device" is relevant to terrible video production.
