*Concentrating on the task, he manages to oversee the replacement of the semi-lucent zwitterion harmonic conduit pipes, though it takes him many many hours of work. He does get short breaks for meals, though he doesn't eat.*
*Meanwhile, Kharas is swabbing the deck, cleaning up spills and messes, and generally performing cleaning tasks. Unlike Anvuss, however, Kharas eventually becomes exhausted by the nearly-unceasing physical tasks, and he barely manages to avoid collapsing thanks to the short meal breaks. Without eight hours of rest, he won't be able to shake off the exhaustion, either.*
*However, both Kharas and Anvuss will receive four hours of rest as is standard for the crew (though maybe Anvuss could try to give Kharas some of his hours).*
