I work mostly the night shift or graveyard shift as it can be called, it can be tiring but it works in with my life when I need to do it. Sometimes I work overnight but am on-call, so I can sleep in a staff room. I think mums and dads work this shift sometimes too! Or people caring for others or those who need to study at night because they work in the daytime or have a family. I know that some people can become ill if they work this shift often and it can affect their life. But often people have no choice, to either work this shift or not earn money for their family or to live:) Good question!!

Yes I do often:)

I just learned this expression here:

I don't, but almost!
