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

Although Robert Butler was the first person who introduced the term ageism (the discrimination against an individual based on his older age) in 1968, we can still see the traces of ageism in every aspect of our daily life. According to Coughlin, an author, and director, it first started in the healthcare system. The roots go back to a traditional belief that everyone has a certain amount of life force, and when it is over, individuals die. Unfortunately, despite the achievements in the medical field, ageism casts its shadow over the practices. Not only health care but also institutions are now affected by it.
Discrimination in employment is an example of institutional ageism; since industrialization, a common belief has become prevalent in America, summarized in the following sentence: One person’s gain results in another’s loss. Consequently, everyone believes that there’s no space for young workers as long as seniors are in the company. Unfortunately, this is the cause of mandatory retirements. No seniors want to be in such a situation. It’s not accurate to say that all these practices are intentional. Sometimes, people are unaware that a simple sentence or behaviour is considered ageism. Instead, most of them are unintentional because ageism is deeply rooted in culture, society, and our minds from one generation to another.
Some accepted idioms or events such as “over the hill birthday” unintentionally convey that after 40 or 50, the person becomes slow and declines to boring old-age. The previous idioms are examples of ageism; they hurt our beloved seniors, whether intentional or unintentional. Sooner or later, we will be old and in the same situation as they are now. It’s time to eradicate the roots of ageism.
