@Galena >whatever mechanical shell I choose to inhabit in that moment
I heard a really cool sci-fi concept that's even better than that:
1) Everyone digitally uploads their consciousness.
2) There's a planet covered in a "mist" of microscopic nanites.
3) At any time, any one of those digital consciousnesses can "possess" a whole bunch of these nanites and form a physical whatever: human (any outfit), cat, catgirl, flying cyborg half-octopus/half-spider.
4) At any time thereafter, you will your current form to dissipate and find yourself back in whatever digital realm you came from.
