Did I just read that?

From Google News tonight: "... people should avoid breathing in smog, the American Heart Association said on Monday."  (link takes you here http://www.reuters.com/article/idUSTRE64A08J20100511, where you can see the phrase repeated in Large Type.)

I'm not sure how people can avoid breathing, in smog or in clean air! That's pretty tricky advice....

Or do they mean it's okay to breathe OUT smog, just not in....
