This will probably be the most rambling and pointless comment I have made in this forum.
I'm not the smartest cookie by any means but I am perpetually curious and the primary tool I use in my feeble attempt to comprehend the universe I live in is abstract thinking and looking at the the big picture.
I do this because I feel that the closer I am to the subject the more distorted it becomes and the harder it is to keep it in perspective.
I often involve myself in discussions just for the hell of it. A way of sparring and playing with words and logic but what I notice is that if I have formed an opinion, from that point on when I see, hear or read anything related to that subject I anticipate contrary information and block or skip over it and I focus intently on anything that could possibly support the viewpoint I have already formed.
This process works well for me when my preferences are positive, constructive, progressive, or helpful but that is not always the case. Some things really bug me and I persist in looking for the negatives. I get stressed or anxious about things like misused statistics or the abuse of power.
So where am I going with this pointless comment?
There is a phrase that I remember reading a long time ago in a Mary Stewart book. Something along the lines that every man brings with him the seeds of his own destruction and I think that is dangerously close to the truth for most of us. Some people destroy themselves with neglect and abuse whilst others achieve the same outcome with worry and stress.
In answer to your question above:
I wasn't dizzy in the past and I have been on CPAP for some years but I am often dizzy now. I don't know why I'm dizzy but it is likely to be either mini strokes, messed up blood pressure or some kind of panic attacks. I've never had panic attacks before but I suspect that they can be learned or acquired because the brain is a powerful device, for good or ill and we are only have superficial control of it.
