Caput Praeterea Durum (Hard Head)

Two snakes fighting over a cool hood ornament

There was a local weekend news story this morning noting that scientists have determined that some people are more susceptible to concussions than other people. It's hard to disagree with that. It's safe to say that more football players get concussions than say, chess players, although the way chess players hold their heads during a match, you'd think they had splitting  headaches. With all modesty, even I have noted that snow skiers get more broken legs than ballet dancers. Not that I'm a scientist or anything. I'm just sayin'.
After all, where would we be without medical science? You could just forget the progress they've made on COPD, ADHT AND UTIs. (My aunt got upset when she saw USD on her medical chart.  She thought she had Ultralow Sodium Dialysate. Turns out it meant
U. S. Dollars.)
It would be great if scientists could figure out some of the heart-breaking medical mysteries like really bad breath or disgusting toenail fungus. They'll get to it, I'm sure. For now,  let's be grateful that we now know
concussions rarely occur in people with hard heads who spend most of their time on the couch.
