I certainly know what you mean there.
With being called out at all hours of the night with the PoCo and the Fire Service (sometimes both), it leaves you feeling really out of wack at the end of the week.
Fatigue is probably the least appreciated impairment out there. The most dangerous aspect is that, long before your body shuts down, your judgement goes away.
Darned good point John, I used to work with a guy that would be working away slowly and you wouldn't know that he was slipping in and out of a semi-conscious state.
He went to get some help as he was not sleeping well at night, it turned out he had a thing called Sleep Apnoea.
It's caused by your breathing being interrupted constantly through the night.
This condition is quite nasty so I'm told, it basically means that even though you do sleep at night the amount and the quality of the sleep that you get is practically nil, due to constantly awaking, so you end up more tired in the morning than what you were the night before.
I wake up every morning at nine and grab the morning paper. Then I look in the obituary page. If I'm not in it, I get up!
Sounds like good advice to me.
