I guess I still don´t quite understand the implications of everything being just data until observed or known. Is my body and brain just data (information) until someone observes me or does my individual unit of consciousness observe itself, thus entering our reality frame?
The whole idea is that your body and brain are never anything more than just data. That you are not what you see in the mirror or feel yourself to be. You are rather your IUOC, your digital mind that does the real experiencing and does what the brain is thought to do, which is observing/experiencing itself as 'you' as its avatar in PMR. You are as real as you ever were or are. But your existence and experience are virtual as they consist of the messages coming to your IUOC over the RWW which provide it with the information to experience itself as you and what you do and experience.
Your mother at 87 and after years of Parkinson's disease could readily slip away at any time and for no special reason. My father died after being gradually and more completely bed bound for 5 years and first diagnosed as Parkinson's until finally diagnosed as Progressive SupraNuclear Palsy instead for the last 3 years or so. I was his caregiver for those 5 years, 24/7. We stood there and watched him die and it took an autopsy to basically say that he died of the effects of the PSNP and had signs of developing Alzheimer's which were masked by his other major problem of PSNP. The only reason that he had an autopsy was that he was in a study of PSNP which was not well understood at that time and the study managers had the autopsy performed. He was very much of an age and condition with your mother. At that age and condition, saying what one died of is pretty much a matter of just taking your choice. Did they die of their major condition or of any one of a large number of symptoms that make up their general condition? So did they die because their heart stopped beating or they stopped breathing or because they had Parkinsons or PSNP or just because it was time and they were ready to go?
I know that in my father's case, he died because my mother released him, finally saying to him please don't stay and suffer any more because I ask it as she had previously been doing. Within seconds of her releasing him that way, he was gone. He was holding onto his life only to please her as she begged him to please not go. Your mother had no one standing over her begging her to stay with them and suffer any longer so she could go when the time was right and she was ready. If you had mentioned her age and condition at the first, I could have told you this much earlier. What you have been worrying about is just your applying limited understanding outside of the range of things to which it applied. You are over intellectualizing and extrapolating outside of the data available. This whole thread has been based upon false understandings as you did not reveal until now your mother's age and condition which you already knew and which were the pertinent factors.
