That is why when people post highly arguable information gleaned from the net, I often tell them not to get their critical information from a source containing mostly dirty pictures. :)Quote:

Trauma often becomes trauma through repitition. But there is something of a catch in this regard. Much of it really hinges on the strength of one's initial reaction. As in the mechanism believed involved in PTSD.Quote:

In a case such as you describe with the bike accident, it is believed that the brain is overloaded or flooded with a greater degree than normal of such hormones, which in turn encodes for a particularly vivid memory. The memory may then be so vivid, that exposure to even subtle stimuli sufficient to elicit the traumatic memory, can cause further subsequent release of such hormones, at possibly even higher levels, sufficient to encode for an entirely new memory. Thus the memories are ultimately compounded in a sense. Trauma in regard to trauma in relation to trauma... The impact often becomes increasingly exponential. Thus, the experience of PTSD. A completely "abnormal" reaction to what might often be considered to most, relatively mild to moderate stimuli in an aversion inducing sense.
On the other hand, people can be repeatedly exposed to things and become quite numb or disaffected to or by them. In large part it really depends on the intensity of the initial exposure. Both the stimuli itself and the person's reaction to such.
