However, it's national No Smoking Day, so if you're seen huddled outside the office desperately dragging on a roll-up, you're sure to be shot a few more dirty looks than usual. It's time to give up (at least for today).  

But, if you need an excuse, science people at the University of Colorado have revealed that men who like men are more than twice as likely to smoke than their heterosexual counterparts and much less likely to quit.  More than 80% of the gays they surveyed smoked daily and less than 30% were well-meaning in plans to kick the death-sticks.  

It doesn't say why it's us particularly who love a smoke so much, but we can't help imagine someone somewhere making a joke about us liking to have things in our mouth.
