Football

"his head was dribbled off the turf against the Bengals" - what does that even mean?

Nit picky. Very. Obviously you didn't see what happened. Tua's head bounced off the turf just like a basketball being dribbled. It was painful to watch. (And to me, just another argument against turf, but anyway.)

As for Hamlin's injury being rare, this former cardiology nurse is going to pick a small bone with you about that too. It's rare-sh, but not as rare as you think. In football, yes. But I've personally seen one case--seatbelted human vs steering wheel in an MVA--and known of several others which have occurred on such diverse occasions as soccer games, baseball games, bike wrecks, and oh yes, lightning strikes. Anything that disrupts the electrical rhythm of the heart.

Some years ago, a young girl from my church was riding her bike with a friend. They were going down a fairly steep hill when the friend wrecked and landed front first on the pavement. When Audrey ran to her, she wasn't breathing. Audrey rolled her over, checked for a pulse and for breathing again, and did what she had learned in Girl Scouts. She started CPR. When a woman came out of her house Audrey screamed for her to call 911 and went on doing CPR. EMS was there within about 5 minutes after the woman called them and took both girls to the hospital. Audrey wasn't hurt but she was shaken up...afterwards. She later received awards from the city and from Girl Scouts. Her friend lived. The doctors said her heart had stopped from the blow of hitting the street chest first--commotio cordis--and Audrey had saved her by knowing CPR.

Moral of the story? Learn CPR. Know where AEDs are. They're basically AI and will tell you what to do once you turn them on.
