You can get a perfectly good supply of vitamin B12 in your diet if you're a vegetarian - eat marmite! ( But that's another thread )Or just about any breakfast cereal, as they all seem to add it to them!
And Lanfranc? I gave up worrying about the circles they build into the unhealthiness ( from a medical point of view ) of the food chain, 'cos I'd had have to stop eating, drinking and probably breathing as well!
