Well, sleep and cruise ships don't destroy and copy your body. Teleportation would be equivalent to being killed the way I see it, until we get a better understanding of conscience at least.

Your body slowly replaces itself. I'm reasonably sure that when you die you have replaced almost all of its atoms at least once.

I've been using the same broom for 20 years! Never needed a new one and I'd never think of getting a new one. Of course I've replaced the handle twice and the brush four or five times.

Eventually, the constituent atoms themselves perform a complete cycle (at the slowest rates) every ~7 years. Some substances (e.g. water) cycle much faster, obviously.

Which tells us that sentient consciousness and identity is mostly about the continuity of a signal across only some cells (nerves), and mostly rides on top of standing waves supported by those special cellular processes, at frequencies of oscillation faster than the underlying polarized/ionic chemical processes.

How do I know? I don't know what happened while on was sleeping. I fell asleep, and perpetually a few minutes later woke up, but my clock told me it was 8 hours. What happened??

You know what happens when other people sleep. It's not an issue.
