Another prick in the wall

I'm going to go out on a limb here and guess that Marc Kaplan of North Fayette, Pennsylvania, is speaking from experience.  In today's Post-Gazette letters to the editor:

Treadmill safety

With the Sept. 17 Health and Science section article "Surge Training Promises to Work Off the Weight," there was a photograph of Ann Caldwell running on a treadmill. Anyone thinking of buying a treadmill and placing it in a small area should know that it is extremely dangerous to have it positioned with the back of it against a wall. In case of a sudden problem resulting in a loss of leg speed turnover, a person can be thrown into the wall. The back of the treadmill should always be facing the open end of a room.

Let's hope that "anyone" never makes this foolish mistake again.
