@Firesysok: I don't know why you are so hostile. I deal with it - I am a father and have a family so I can relate and understand that problem very well. I only wanted to inquire if people see that as a problem in their job. My wife knew when I had an early clinical duty (physician) next day she would leave me alone and take care of the kids at night if possible/needed so that I could be well rested for the next morning.
Whom would you rather have doing your brain surgery at 7:30 am: the well rested guy or the guy who woke up three times at night to take care for the crying baby...?
