The administration at Anglia Ruskin University in England has saved graduates possible injury by banning the throwing of hats at graduation.
The university website tells graduating seniors that they are not to throw their hats in the air, "...as this not only causes damage to the hats, but can also cause injury if the corner of the hat hits the graduate or others who may be nearby."

(Fortunately, after an official intervened on her behalf, the city council reduced their mandate to requiring only adult supervision... and insurance, which doesn't exist.)
Since we can't take care of ourselves, it is so good to know that there are others who want to do it for us.

Man, am I glad to be alive. I've been living-on-the-edge this whole time and never even knew it.
