The shielding genuinely works. What is much harder to find is evidence that contactless skimming is a meaningful source of card fraud — and the cards themselves changed years ago.
Home blood pressure monitors are often accurate devices producing wrong numbers, because the cuff supplied does not fit the arm using it.
A sinking office chair gets thrown away constantly. The failed part is a standard-taper gas cylinder, it costs about as much as lunch, and swapping it takes twenty minutes.
Tread depth is what gets checked and age is what gets missed. Rubber oxidizes and hardens on the shelf, so a tire with full tread can be past its useful life before it is fitted.

Everything about choosing a baby mattress runs against adult instinct. Firm feels unkind and is the safety requirement, and a mattress that fits loosely is a hazard regardless of how good it is.
