Sleep Deprivation

For the life of me I can't understand this sleep deprivation thing. I will get up at 4 am to hike the entire day and never feel the effects. On weekends, when I can sleep in, I'll awaken at 7 am on my own with no ill effects. But Mon - Fri when the alarm goes off at 7, I'm completely comatose. And if it's a day like today, where I had to arise at 6:15 to be at work for a safety meeting, well, I'm zombi-esque!!
I'm sure that as the day wears on I'll perk up, but for now I'm running on...coffee I guess! Days like this are "zero tolerance for stupid" , and it started poorly in that regard. You pull my a** out of bed early to sit in the shop and listen to someone say "Okay, we need to work safe. Any questions?". I'm sorry, but I think I would work more safely if I would be allowed to sleep longer.
I'm sure research would prove that most violent acts are commited bt people who didn't get enough sleep. Imagine if Charles Manson had just been allowed to sleep in that morning. Would Pearl Harbor been avoided if the Japanese had been able to get more sleep - probably.
I'm getting tired just typing this. I think I'll grab some more coffee and walk around the shop and hope, no pray, that I can avoid dumba**es for awhile. But then I do work with Juan, so that diminishes that hope. Later!
