I help millions of people every day, but am taken for granted by all but one.
My sole companion and I are frequent travelers.
I don't work night shifts or sleep.
I have several breaks, all of which I use up fully.
People depend on me, but I never get stressed by it.
My living conditions are pitiful.
What am I?
Good luck guys! If you could leave a rating out of 10 for how difficult this was, I'd really appreciate it.
