I am happy that concussions/head injuries have been getting this attention, more research is being done, and awareness has been significantly heightened. I have no doubt that there are significant brain injuries problems in the NFL, and this subject was overlooked or swept under the rug in the NFL for decades. I am glad that kids sports, high school and college sports have development more awareness and protocols.
However, I don't understand why there don't appear to be alot more, or even any, lingering impacts of concussions/head injuries from anyone among my family, friends and anyone I ever played with or knew. Almost everyone I played with in high school and college, as well as my siblings and cousins, were stunned, dinged, and concussed--multiple times--and even knocked out on occasion, but none of them have or appear to have lingering affects, to my knowledge.
And personally, while I like the awareness and the protocols that keep kids from going back into games after they get dinged, my view is that the protocols that have developed have gone too far. With even minor issues, for which there are very few initial symptoms (which may subside in a day or so), it's very difficult to get back into competition for about 10 days.
Doctors and others often advise that kids not watch tv or use their cell phones, which, of course, they ignore. They may be advised not to go to school, which can be a negative for kids who are not top students or who are struggling and cause them to get behind. For a more serious concussion, maybe. But for fairly minor dings/stuns? I wonder.
Due to the protocols and the baseline testing, kids have learned to goof up some part of the baseline test, so it's not set overly high (and hard to recreate after a minor (or I suppose major) head issue).
