There is objective reality and there are those who wilfully, or otherwise, deny it. Which of the two applies to you?
There is no such thing as an objective reality because everything we perceive, we perceive through the filters of our own minds. You should read up on on neurology. The same applies to you as to me. We see the world though our filters excluding evidence to the contrary, particularly as we age and our brains atrophy.
Like I said you really should look into neurology. It is a fact that our brains atrophy as we age. It is a fact that we process information using filters and that we do so selectively. I am surprised that an old hand like you wouldn't have noticed these very simple facts with or without doing research. What else haven't you noticed that the rest of us have? Objective truth perhaps?
