The fear of elevators

Sharks kill less than 20 people per year - elevators accidents 27.

Of course, reduced exercise from taking the elevator instead of the stairs is almost certainly a bigger health hazard than elevator accidents. Yet, I wonder if you could strategically use advertising to try to spark fear of elevator accidents in order to achieve the former - increased exercise. Think of it as "shark week" for elevators but to achieve a public good. Consider the following brief, relatively gruesome tale of one such incident:

As Nikaidoh stepped onto the elevator, the doors closed, pinning his shoulders. "He tried to pull back and he couldn't," Steinau told HPD officers. "The doors wouldn't open."

... Nikaidoh struggled, trying to shrug out of the elevator, or possibly pull himself inside ... but the elevator kept moving upward. The ceiling sliced off most of his head. His left ear, lower lip, teeth and jaw were still attached to his body, which fell to the bottom of the elevator shaft, as the elevator continued moving upward.

(And, of course, this is far from the only tale. Given a large enough group of people, there are lots of examples even of rare events).
