A scenario not mentioned: my meat self is augmented cybernetically. The augmentations provide for improved, then greatly improved, then vast cognitive enhancements. Additionally, I gain the ability to use various robotic bodies (not necessarily androids) and perhaps other cybernetic bodies. My perceived 'locus' of consciousness/self disassociates from my original meat body. I see through whatever eyes are convenient, act through whatever hands are convenient. The death of my original meat body is a trauma, like losing an eye, but my sense of self is uninterrupted, since its locus has long since shifted to the augmentation cloud.
