I fail to accept the notion that people are stupid sheepish weaklings that have no willpower over their own body and mind. Some might believe this and then act in this fashion, but most have the potential to do almost any change with their life, be it eating habits or something else. I stopped smoking after university, not easy but perfectly doable. That was 12 years ago. No cravings anymore or any thoughts. Detest the smell like all others (that's actually easy part). Same for very good friend, he never touched cigarette and he was quite a smoker back then, till one day when he stopped just out of blue. And we're nothing special, just common folks. If we could do it, most can do it too. But not with the attitude you describe, that's for sure. Let's not try to save humanity in the first step, and just focus on yourself. Self-discipline is not a curse word, it means a lot of mental strength and power in long run
