If you spend any time at the grocery store, you’ve likely spent an ample amount of time looking at expiration dates. I understand the need for them, but I’m honestly confused about why some products need one. For example, the other night I was getting ready to put on the nose strip I use to keep my airways open while I sleep. I’ve used them for years, but didn’t realize they had expiration dates until recently. Why? What part of this product can expire? I understand when food needs them. But they’re just products marked with those dates, and it makes me wonder…
