What really bothers me,is when I've nodded off and wake up to my finger on the scroll down key and have no idea what I've been looking at.
Two years ago,I changed jobs so now I work day shift with weekends off.For six years prior to that I spent my winters in charge of the snowmaking and grooming crews at a ski area.
This was all night shift work.I would leave the house at 10:30 at night and not get back home until 11 or 12 the next day.I would try to go to sleep,and would wake up three hours later and not be able to get back to sleep.Reading didn't help.Playing music didn't help.It soon began to take a toll on me.I made mistakes.And when you make mistakes while driving a piece of equpment that weighs 8 tons and is 11 feet wide at the tracks those mistakes can be big ones.Sleep deprivation is a very serious disorder.
And all that was at $7.00 an hour.Wasn't worth it.
In staying up to be with the Mudcat cyber-family,I have webtv. So my screen is 10 feet away,and is a 27 incher.I have other things to occupy my vision to break things up.
Praise,what you were talking about with the strobe effects is a very real phenomenon.I studied it in physiogical psych.,but can't remember the name.It affects drivers when there is a line of trees along side the road and the sun is shining through them.It has also been proven to have affected helicopter pilots as the sun shines through the moving rotor blades and has been named as the cause of some crashes.
Anyway now I'm usually in bed by 10 or 11 and sleep the night through,with many wonderful dreams.
