Obesity, smoking, class and everything else

I've just read a few good articles from Velvet Glove, Iron Fist.

This one, in particular, struck a chord:

If you had told the average person in 1980 that meals should be taxed to deter purchase or that food advertising should be restricted to prevent obesity, he would have laughed in your face. That would be true even if the average person was a member of the British Medical Association.

How did things change? They changed, in no small part, because the campaign against tobacco crowbarred open a door that allowed the regulation of any human behaviour that might have the slightest impact on their or anybody else's health. Once opened, it is a door that is very difficult to close. I don't expect it to close in my lifetime.

And I'm only 34.
