Interestingly, just days before the NFL's decision to suspend the use of impact sensors
was announced, my local paper, The Boston Globe, came out with a powerful editorial in which it urged college,
high school, and recreational leagues in contact and collision sports to consider mandating use of impact sensors, or, at the very least, experimenting with the technology, to
alert the sideline personnel to hits that might cause concussion, and to track data
on repetitive head impacts, which, a growing body of peer - reviewed evidence suggests, may result, over time, in just as much, if not more, damage to an athlete's
brain, as a single concussive blow, and may even predispose an athlete to concussion.
As long as the
brain continues to perceive danger, the sympathetic nervous system triggers hormones to
be released and the body remains revved up, activated,
on high alert.
Identifying blog posting topics in advance helps authors put their
brain on high alert, searching for relevant ideas for upcoming blog posts while the authors
are performing other daily activities.
Whether because of post-traumatic stress disorder or the many adaptive behaviors that victims use instinctively in threatening situations, the traumatized
brain is constantly
on high -
alert, particularly its lower regions, where survival instincts originate.
