Michelle,

I took a look at the site. I can't say if it's serious or not, but it appears to be serious. If it is, as far as I'm concerned, those guys suffer from paranoia...

While they're at it, they should be concerned by human breathing: we do release toxic carbon dioxyde! :) The only solution: stop breathing!
