It never ceases to amaze me that otherwise smart people will sit down to a meal and eat until they are physically incapable of stuffing more food into themselves. Every single time. The concept of "meal" is synonymous with eating until full, rather than eating until no longer hungry. Further amazement comes when these same people, now obese, don't immediately do something about it. If you had any other terminal condition, you would do anything in your power to fix it. If you're fat, you just ignore it and get on with life. It all seems so simple, watching from the outside.
