I was trying to affirm and explain your observation - not in any way to discount, dismiss, or disqualify it.
The article does not explicitly address the issue of "focused attention" further delaying your body's response time to a pain stimulus - rather, the gist is that, by circumventing the brain (and thus its higher faculties like "consciousness" and/or "awareness"), it permits your body to respond quicker and reduce injury, since the nerve pathways are shorter (I believe that they are also myelinated - sheathed - and thus faster transmitters).
Regards,
I appreciated the article that you linked to very much and took no offense to your observations. My response to your post was meant to be humorous and not critical in any way.
In every instance where I have received fairly serious injuries there was a delay between the time that the trauma occurred and the time when I realized how bad that it was. This was especially true when I was engaging in competitive endeavors such as bicycle racing. After a fall I concentrated on straightening out my bike and getting back in the saddle. I typically, did not realize the extent of my injuries they started causing me difficulties further down the road.
