Leylandii issues

Re: Leylandii issues

It was believed that blue blood comes from the bluish coloured blood which many of the nobility attained from silver poisoning via their cutlery. Since this was not understood, and the poorer members of society could not afford silver cutlery, blue blood was said to be a sign of noble heritage.

By whom was that believed?

Vide Argyria at Wikipedia - link - and then you might understand that the skin changes colour, not the blood and also that ingestion of silver from cutlery would be far too slight to cause the changes.

(I occasionally have to correct the question setters at QI, too.)

It was one theory held back in the day, I never said it was true
I've heard about colloidal silver turning the skin a bluish gray

It's actually from the appearance of blue veins near the surface of untanned skin that was as pale as alabaster.
