Rather late, sorry. Addressed to answer Naomi at 13.54. Just to say that my answer has, indeed, been reinstated. Life problems intervene, I'm afraid.
However, I am now very reluctant to post an opinion on the Science page as I am not a scientist (although my daughter has a degree in Chemistry from Durham). I am also wondering about offering the benefit of advice on the 'Body & Soul', say, about a health condition from which I, or someone close, have suffered. It is a very concerning development. Reminiscent of the EU actually! :)
