Bottled water does not expire in the way food does. The date is mostly about the bottle’s quality, not your health. If the water tastes fine, smells fine, and looks fine, you’re good. Your body has survived worse cafeteria lunches.
So next time you find a forgotten bottle under your couch, don’t panic. Take a sip. If it tastes like your grandma’s attic, dump it out and move on with your life. And maybe, just maybe, buy a reusable bottle and save yourself the existential crisis. Your future self—and the planet—will thank you.
