When you are 68 years old, I think it takes a lot of courage to go to rehab. It would be really easy at that point to just say forget it, I don't have much time left so why bother. Sly Stone has checked himself into Promises for his addiction to crack. Unlike most celebrities, Sly plans on staying a full 90 days to give himself the best chance of getting and staying sober. I also think he wants to have one last tour around the world and it is tough to do that when you can't let go of the pipe.
For the past year or so, Sly has been living in an RV on a residential street and basically getting supplies from a couple who let him park in front of their place. That is quite the fall. Hopefully this will get him back on his feet.
