WTF - we have had thick fog in the UK for the last few days. A gale blew it away today thankfully. And I used to have asthma and last two nights, a little wheeze was back and I haven't had that for years, I was actually lying in bed thinking damn, I should have saved a blue inhaler for these rare instances. Thought it might have been because I was laying off alcohol for a could of nights (could still be that).
