I think people generally want to enjoy their lives. I have a friend that keeps his house at 60F in the winter. I think you can argue that I'm not going to die at those temperatures or experience hypothermia. It's quite unpleasant nonetheless. During the summer if it's hot indoors I feel miserable and tired. A lot of us could live a more simple life (i.e. no cars, fewer children). But humans are attracted to comfort and the ability to pursue their dreams.
