This is how it feels to be Anakin Skywalker, forever:
You can hear yourself breathing. It comes hard, and harsh, and it scrapes nerves already raw, but you cannot stop it. You can never stop it. You cannot even slow it down.
You don't even have lungs anymore.
Mechanisms hardwired into your chest breathe for you. They will pump oxygen into your bloodstream. Forever.
Human Citadel Officer: "I need you to stop and take a deep breath, sir."
Angry Volus: "*Hrrk* You're mocking *Hrrk* me, *Hrrk* Earth-clan!"
