Hi there,
I thought that this would be a nice change myself, after a "coronary incident" a few years back, I looked to do the admin side of the Lines dept of the PoCo I work for.
To be honest mate, it nearly sent me around the bend.
As soon as an "urgent" call for someone to help with a given job comes in, you want to get out there again, as much as you fight it.
Dis-regard any thoughts of "I can do this", you are in an office now, hand your tools in at the door.
