Where my existence will be, I have no idea. But if I remain a good human being till the end, I will definitely find space in the minds of my children, friends and whom I helped in life for many, many years.
I expect to be nowhere. I'm hoping to be nowhere. Any thought of being anywhere else, scares "the hell out of me," pardon the pun. Mind and soul are one to me. When my brain stops functioning I hope I cease to exist. NOW, if in the future, cognitive functioning can be preserved as it was with Spock in the glass globe on the table beside him, now that's another story. However, the mind existing without a body would be hard to conceive. I think when sensory input stops coming in, your mind deteriorates. So the mind-soul connection to me makes it impossible for me to imagine. My highest hope is that when I die, I cease to exisit.
