To me, the Other Side is the opposite of Life. What sparks Life? And when that spark goes away, where does it go? Does it go to a life yet to come? Maybe the Buddhists are right when it comes to reincarnation.
To put it another way, my parents had a combined lifespan of 132 years. Yet, death will hold sway for however long until the End of Days. Which state has more sway...life or death?
Ghost, I just try to filter out the obvious bullshit, apply the facts that I know, and use common sense and reason. This seems to help me stay out of trouble and be moderately successful in life.
My understanding is that the brain defines a person. It can be artificially manipulated by drugs or surgery to change our thoughts, memory, and personality. Despite reported pseudo-science, there has not yet been any evidence for a soul. Destroy the brain and the person goes with it.
That's all I know about it. Anything else would be wild, unfounded speculation, or in other words, just bullshit. And I have no use for that.
