Some interesting quotes there... “The fact that everyone is born incontinent is probably one of the main reasons for shame and embarrassment over incontinence later in life” - well, true to an extent, but everyone’s also born bald, toothless and unable to walk, and they’re not seen as generating the same level of stigma in older age as wearing nappies as an adult.
It’s interesting that they sold Depend products including the full nappies on pharmacy shelves in the late 80s/early 90s. I never saw them, obviously didn’t sell well enough. Though I remember seeing Boots Staydry adult nappies on the shelves from my early teens onwards, which was early 90s.
