Since I don't have the full story, I can only speculate. However, key points could be related to Nikki Sixx's past issues, like his battle with substance abuse. Then, there was probably a moment of reckoning where he decided to turn his life around. This new chapter in his life, the 'life after death' part, might involve his success in maintaining a healthier lifestyle, his continued work in music with a new perspective, and his role in inspiring others to face their own demons and make positive changes.
The key points might include a significant turning point in Nikki Sixx's life. Maybe it was a health scare or a realization about his self - destructive behavior. After that, he likely made changes, perhaps in his lifestyle, career, or relationships. These changes would be central to the 'life after death' concept, representing his new start.
