I’m a daily weigher who mostly trusts the trend line. Last month I found a spare pen in my gym bag with no date visible—the label had rubbed down to blank foil.
Instead of guessing, I checked my notes: I’d logged the fill date as a calendar event, and my fridge thermometer has been boringly steady. I still set that one aside. Not because I think one smudge equals doom, but because my calm comes from knowing the inputs.
I’m curious how others handle this: Sharpie date, notes timestamp, pharmacy sticker, or toss it? I’m trying to keep my data honest without turning a missing label into a whole mood.
