Completely agree with it..... but not for the safety aspect.
The "short tail and huge knot", to me, looks utterly retarded.
At school there was a broken tie pinned to a board that said something along the lines of "This is all that remains of the tie that a pupil who was not wearing an apron once wore. Thankfully he was strong enough to push himself away from the pillar drill. He didn't even think of pressing the emergency stop button."
Now, I'll agree that it was his own fault because he was not wearing a tie, but still. Accidents happen, and schools don't want to get sued.
