I'd imagine that if you can be revived, the reasons you want your gut bacteria back would no longer apply.
What's your line of thought?
My guess is that if you're being revived as something much like your current self, you will at least need simulations of gut bacteria.
I think it's past time for another Stupid Questions thread, so here we go.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Please respect people trying to fix any ignorance they might have, rather than mocking that ignorance.
