To anybody fearing or fear-mongering "chemicals" there is no such thing as "chemical free" because "chemical" means effectively nothing as it is used in the media, because literally everything is chemical, everything is made of chemical. water is a chemical, it has a chemical formula, which most people actually know, H2O, dihydrogen monoxide. Humans are literally made of chemicals, it's really annoying every time people say "chemicals are bad for you" they can't be, some are, but to avoid all "chemicals" would be impossible because proteins are chemicals, fats are chemicals, sugars are chemicals, so no food, as previously stated water is a chemical and you can't last more than 2-3 days without water. In fact, death would come within actual minutes without chemicals, because oxygen is a chemical, everything in the air is chemicals, you would go brain dead in actual minutes without "chemicals" please just take a second to calm down, and think, head on over to Google or Firefox or bing or yahoo, do people still use yahoo? Just go to any search engine and search "chemical" and you may not understand everything immediately but it should be pretty easy to see and understand that there is nothing wrong with "chemicals"
