I also have no idea why some people seem to think that incontinence is connected with either old or mentally disabled or otherwise bodily "handicapped" people (if inappropriate expressions, please forgive me, I don't want to offend anyone!).
As many others, I'm also a quite active person, I'm in my early 60ies, quite slim figured, no visible issues (except of the loss of a lot of hair on my head) - I'm only fully bladder IC. I'm sure very many more people have continence issues where nobody else would ever think of - it's really time that the awful stigma gets cancelled!!
