We go unconscious to save our self from further trauma not because of damage done. People going unconscious in battle have survived true the ages while people eating shots until they die make few children. Brain shuts off to avoid further damage and you live to fight another day. The Alistair Overeem factor.
You just made that up, or heard it from someone else who made it up and just accepted it with no evidence.
Saying unconsciousness from head trauma is adaptive is like saying bones break to protect our limbs from damage through continued action. It's a breakdown, not a protective reflex.
Going unconscious in a violent situation is obviously not a good thing, particularly in our evolutionary history when raids between bands were typically genocidal, to say nothing of encounters with animals or personal confrontations.
In any case, no one thinks losing consciousness from a heart attack, stroke, hemorrhage, asphyxiation, infection, hyperthermia, hypothermia, poisoning, burns, seizure, diabetic shock, electrocution, etc is a good thing, we recognize it as a sign of serious danger. But retards, like you, think losing consciousness from getting our brains mashed is A-OK.
As far as Overeem is concerned, we know nothing about his neurological state, except maybe his speech. He may be suffering the effects of brain damage on his mood, memory, general cognition, etc. Furthermore, it has been observed in football players and the like that the symptoms of brain damage can emerge or intensify later in life.
If you want to use fighters or athletes as evidence, you have to include that entire population, and there's obviously far more guys who show pathology following head trauma than there are guys who seem to handle it OK.
