I wanted to add my husband's point of view. He's very much afraid of death, because he's terrified of ceasing to exist. I'm not sure why, it's difficult for me to understand since I have almost the opposite perspective. It's a failure on my part I suppose and I tried to ask but honestly I still don't get it. It's not that I can't understand an opposite point of view. As thought exercises, I can imagine how someone came to X, even in horrible cases or extremist views you can see the road map, so to speak, of how someone got to that conclusion. However, I still haven't figured out his point of view.
I also can't discuss matters relating to the self and ego with him, theories by neuroscientists and Buddhists. To him it's all very scary and will shut down/get irritated if it's brought up. I also pointed out that he didn't exist before his birth and he said he knows and that's terrifying too.
