Shift worker...or not?

[Harry72]

Personally in my case(16yrs) I am more alert at 3am in the morning than 3pm on day shift, I prefer night shift too day shift I find it a lot easier. I wish I could just work nights.
But many of my work mates are the exactly the opposite, cant keep their eyes open... not good when driving cranes playing with molten metal!

Night shift my choice also but only because it means less phone calls from the client's office and for some reason night drilling supervisors are generally more Geologist friendly than their day counterparts. That said, at 3am I'm at my worst and often have to have a power nap to take me through to 6am and the morning reports.
