These days it's not the air being sucked out my lungs I worry about that I worry about when I go on trains - it's that I'll get stuck in a load of mobile phone users.

"hello? yes I'm on the train. about 20 minutes? the medication? well, I've been cutting down because the attacks haven't been as bad - I'm on quite a busy train just now, and I feel fine."

I DON'T WANT TO LISTEN TO SNIPPETS OF YOUR LIFE!!!
