I have an addicted friend. You'd think he'd be too mature for this particular addiction, but it's a sickness that strikes a lot of men of his age and financial position. My friend is perfectly aware he's both addicted and forever engaging in self-destructive behavior, and while he's always a good sport about seeming to take the counsel of friends, he keeps right on indulging his addiction. Is he stupid? Is he too far gone? Can anything be done to help him, or should we all just stand aside and watch his sad, slow death-spiral as he crashes again and again, never learning the essential lessons that he should have learned years ago?
