LOL, no worries. "The big smog," I just watched a video recently about how the London smog literally killed a bunch of people one time. And not like "they got cancer after years of exposure," but like "it didn't lift for days and people asphyxiated and they passed new environmental laws because of it."
Of course, in the States, one of our blood sucking creatures (politician), recently said that our air was "too clean for optimum health."
Yeah.
That guy should suck on a tailpipe and see how he feels...
