Say that you were swapped back to the past, be it yesterday or 10 years ago, without having any memory of having lived in the future. Would you consider this some sort of death? After all, your current self would fall out of existence. Whatever is your stance on this, it brings an interesting point; it could be said that we die at every instant since what we once were is no more, that is our current self is constantly changing. Do you think this is tenable or not? Give out your reasons.
