Is it expired?
What’s the first thing you look for in a bottle of water? Some people search for adjectives that describe how “fresh” the water is, such as “mountain spring” or similar. However, you might be surprised to learn that the water we drink (and secrete) every day isn’t as fresh as we might think.
In fact, the water that we do consume is probably older than our solar system. Yeah, let that sink in, and turn off the faucet while you’re at it. Even though water is renewable, much of the world’s lost water goes underground or enters the atmosphere. Odds are that we drank the same water molecule as the dinosaurs!
