This silent documentary is worth watching. First, because it is one of a kind. Second, because it talks about something we are all being affected from. Third, because it's informative. I didn't know about all the pro-biotic stuff, that they can help us live better and fight the disease. The way that Italian professor explain those things is quite fascinating. And it's scary to know that another pandemic could hit the world anytime. Yes, that's the scary part. We should really do our best to prevent that from happening.
