Ah yes, dentists. The people who used to hold X-ray films in place with
their fingers, day after day. They certainly know an occupational
health risk when they see it.

Also mercury amalgam is far from an acceptable risk to the dental
nurses involved in _preparing_ it from mercury (maybe dentists too, but
they're paid enough to not worry about them).

Heard the latest? That Torricellan barometers may be banned?

Apparently our European masters didn't think about them when they banned
mercury oral thermometers - until some **** asked if barometers would be
included!
