Smoking and Obesity

The media keeps saying that today’s kids are obese and that today’s parents may be the first generation in history to outlive their children. Yet, in the United States and Canada, smoking and lung cancer are on the decline, which makes me wonder whether cigarettes would keep our teenagers and twenty-somethings slim, allowing them to outlive their parents (rather than the other way around), even though they eventually die of smoking-related illnesses.
