As a quick aside, however, I see the BBC has described me on its website as:
Chris Snowdon: Smoker and author of 'Velvet Glove Iron Fist; A History of Anti-Smoking'
Does this suggest that smoking is now so rare and exotic that it's worth calling attention to? (There are only 1.2 billion of us after all.)
Or is smoking now classed as an occupation? If so, I'd just like to say that I'm available for work, I have my own lighter and I'm prepared to travel.
