If all us writers got all our apostrophes in the right place, editors would be out of their jobs. So why do they get so picky? It keeps them in work. I should know - I was a copy-editor myself in a former incarnation! Anyway, what I really wanted to say was thanks for the public service announcement about when to call an ambulance for an asthmatic, because I am one and I've often wondered. I don't get it badly; have only been to hospital with it once; but it feels like a really useful thing to know.
