Mental work alone can’t make you tired. Apparently, a few years ago, scientists tried to figure out how long the human brain can labor without reaching fatigue, the scientific definition of which is “a diminished capacity for work.” To their amazement, they discovered that blood passing through the brain when it is active, shows no fatigue at all. If you took blood from the veins of a laborer while he was working, you would find it full of “fatigue toxins” and fatigue products. But if you took a drop of blood from the brain of a brainiac and a scientist such as Albert Einsten, it would show no fatigue toxins whatever at the end of the day.
(On this note, it would actually be interesting to take a drop of blood from the brain of all law professors and law students and see how much their “fatigue toxins” are...)
This only means to say that the brain is utterly tireless. It can work “as well and swiftly at the end of eight or even twelve hours of effort as at the beginning.”
(Is this even for real? That sounds like a high-tech computer to me. How come I feel so tired after reading the third assigned case for my ADR subject.)
The question then is what makes a person tired? According to psychiatrists, most of people’s fatigue is derived from their mental and emotional attitudes. Worry, tenseness and emotional upsets are three of the biggest causes of fatigue.
(I am probably fatigued at this point not because of all the reading I did but because of my persistent anxiety of what to write in this blog and of fear that I may not be able to wake up later and get locked out for class =)
Oh well! I bet you law students’ “fatigue toxins” are way higher than law professors’ are.
