Silent killers

I do love listening to the radio here, but they have ads on at the moment that are really troubling.

Asbestos, is , apparently, a silent killer.

4 plumbers a week die from asbestos exposure. I have this vision of dead plumbers all over the place.

5000 artisans a year in the UK drop dead from this terrible scourge.

All I can think of are all the South African houses with asbestos roofs, asbestos heaters, asbestos wall filling, asbestos garages.... is a wonder I survived so long.

Thank god I'm not a plumber.
