It's just a science-fiction adventure TV show, Kitty. I doubt the writers had exact science in mind when they wrote it, I was just using it as an example.

They grew these flesh bodies that were just bodies without a consciousness or brain in them, but they needed them to do really dangerous work. So the workers would lie down dormant somewhere safe, with a machine that transferred their consciousness from their real body into the flesh body.
