The word "physiognomy" comes to mind. There may be some good reasons for this heuristic - there are some aspects of attractiveness that are completely out of peoples' control; however, in the general case, a lot of a persons's physical attractiveness comes down to choices that the person makes. For example, if you can't control your self in how much sugar or alcohol you consume, you will become less physically attractive. Often, if you are making unhealthy choices, your body will complain. And if your mind is unwilling to sacrifice personal pleasure for the good of your own body, that might be a good sign that you will be unwilling to sacrifice personal pleasure for the sake of other people.
