8 Things Everyone Gets Wrong About 'Scary' Chemicals
8. It’s Possible To Have “Chemical Free”
Nope. You just can’t. Everything, and I mean absolutely everything, is made up of chemicals. One dictionary definition of the word chemical is “any basic substance that is used in or produced by a reaction involving changes to atoms or molecules”. That essentially covers everything, including boring, everyday things like water, oxygen and nitrogen.
In fact, your body is one big soup of chemical reactions, from the glucose that your cells use to generate energy, to the haemoglobin that allows oxygen to get around your body, to the DNA in every single cell.
Unless you’re some sort of weird pure energy life form living in the deepest reaches of outer space (or possibly inside the Large Hadron Collider) you spend all day touching, eating and breathing chemicals. Like the song says, let it go.
