The problem with addiction, of any kind, is that unless the addict is willing to change and freely enters these facilities, they're more than likely going to relapse.
Now, was Tiger an addict or just a rich, dumb kid with no sense of propriety or moral conviction? Ones ability to hit a golf ball, hit a baseball or hit the three pointer, etc.....has no bearing on ones intelligence.
As to what Tiger is doing right now? Who cares!
