That is actually a very interesting and effective point, I never thought of it - but the more I think of it the more it makes real sense. For me; They built a new Dominos pizza place across the road from my apartment, and I can't stand it - because I know just how much I like to sit in front of the TV, with a 3000 calorie large stuffed-crust pepperoni and a coke and watch Netflix or whatever. I've done that once in the year since it's opened up, but I've had to really dig deep on a lot of occasions to resist the temptation to go in and gorge. Honestly - I wish someone would swing a wrecking ball through it, because I don't want to live in a world where I'm being tempted left right and center to gorge myself, I shouldn't need to maintain a force-field of self-control just to stay healthy. Sometimes it feels as though the environment is trying as hard as it possibly can, to make me take bad choices and become unhealthy, to stay on the straight and narrow sometimes feels like a very difficult battle.
