The Bloor Street Viaduct used to be the most popular place in Toronto for the suicidal to jump off and end it all.
Until the city fathers had an ugly fence built around its sides to spoil the view, on the basis that the bridge, and not the mental state of the unfortunates who jumped off it, was the problem.
Now people are getting electric shocks just walking across it.
Electric shock therapy is still an effective treatment for severe depression.
If the city had known that, they could have saved themselves millions just by turning up the power at night. By the time the suicidal folk got halfway across, they wouldn't want to jump anymore.
