Ok, give us a clue. Where are you going with this? Just a teaser.
Not a teaser, it is just I can't figure out a way to dump a wide Excel sheet to ONE post. This will show some overlap on the head injury, hospital stays, a plane crash, etc. in this time frame. No tricks, it is just that I am chopping up a wide Excel to get it out, then invite others to search valid news reports to see if there is anything more to the concussion story.
