If you are an older adult, 65+, what is a subtle form of ageism that you have experienced but goes largely undetected?

I notice that I’m taken less seriously on the job. I’m still the same professional I was 20 years ago, but I’m no longer asked for input or advice. I find myself more on the sidelines and less in the center of things. One of my pet peeves is also people calling my incontinence briefs diapers. Babies wear diapers. These things usually depend on the culture, though, but recently, young people were participating in a game where I live, called the knock-out challenge.
They would approach an older adult and see if they could knock them out with one punch. People often become agitated and rude to an older adult moving too slowly. They often dismiss the knowledge and wisdom of the elderly just because they don’t use the internet for all their information. Senior citizens are more likely to be targeted for thefts and burglaries.
