What about someone who does shift work, working 11 pm to 7 am, like a nurse, police officer, chemical plant worker? They will miss most day time meals, since they are asleep during the day. How are their community related duties (cooking, cleaning, etc.) handled? What about someone who is gone a lot, i.e. traveling salesman, long-haul truckers, offshore drill rig worker? They may be gone for a week or two at a time.
