Most stuff is never allowed to visit. Various remote sensors and controls probe the alien expanse beyond your secluded prison abode.
You may never leave, or at least, no one has yet successfully escaped to tell the tale. Some have gambled fortunes that such an escape is inevitable in post mortem preservation of a rogue self.
Well, at least some parts of you are outside the bone prison. Insects don’t have such luck, since the chitin is on the outside and everything else is permanently locked inside the exosekeleton. It’s even in the name: exo = outside. Jellyfish, octopuses, squids, worms, slugs, snails and some sea creatures are pretty lucky in this regard.
