That is craziness. I'm sorry, but kids who grow up suffocated by rules and not being allowed to just be kids and have fun grow up with a lot of issues. Safety is good, but not at the cost of their social/mental health.

I'm probably just sensitive because I felt strangled by the ridiculous rules in my high school, but I really think kids should be allowed to play and talk and be kids... That's why you have teachers watching, they took care of the choking incidents, everything was okay. No need for such extreme measures.
