Mindriot said:No offense but the guy 10 stories up walking on 8 inch thick Steel Beams has BOTH mental and Phisical Fatigue. You people who complain about Mental Fatigue only have that one type of fatigue. People who work in construction or other laboring and Dangerous jobs usually have both. The mental and the physical. Just becasue these guys walk 10 stories up all day doesn't mean they are used to it. It's both Mental and Physical.
Sorry if I sound like I'm bashing, But it's not as significant as a construction site. Sorry man.
At the end of the day all jobs are fatiguing. If they weren't then people wouldn't be paying you to do so.
