Divers who do not drop their weights in an emergency are divers
who were never taught to drop their weights in the first place. That
doesn't mean that they were never told to drop them. It also doesn't
mean that the divers didn't get it right on a written exam.
Divers are taught to drop their weights only when they are made
to drop them during training. They will get it engraved in their heads
when they've experienced what it feels like. Now having made a student
drop his or her weights (the right way to train them), the instructor
is left with a weight belt on the bottom. He or she needs to retrieve
it. Multiply this situation by three (because the student should be made
to do it three times), then multiply it times the number of students in
the class, and you will quickly see why beginners are not trained to
drop their weights but are only told to drop their weights. ... You
could call these instructors lazy ... you could also call them "bad."
