ptsd is not defined by the level of psychological impact though. Not everybody who goes through bad stuff gets ptsd.
So it is not a good gauge to define what is traumatic and what isn't.
Actually yeahh it is... nobody gets PTSD from baking cookies or hitting bag.
Not everyone who suffers gets PTSD, but everyone with PTSD went through something traumatic. That's the "Trauma" in the name of the disorder.
i.e. Not everyone who eats gets fat but that doesn't mean fried chicken isn't fattening....especially when it's a common meal among the obese.
That's why it's do easy to find PTSD sufferers after rapes, assuaults, etc.
But you can't find a fighter who got it from MMA.
There a whole list of common PTSD causing events....
