I often wonder if it is this attitude that has caused the rise in fat and lazy people.
I'd sooner blame the "choices" of food we eat.
But people often do not care enough to change their "choices", even when the negative results are obvious. There must be a reason for that.
Yes, i'm pretty sure being courteous is what causes people to become fat and lazy. It has nothing to do with diet, exercise or a sedentary lifestyle.
The first thing that happens when you start being honest is that you realize what a dick you really are. Once you see that, you get to change it, instead of hiding it like all the sleepwalkers.
