I need your help too... I'd like to know what y'all think of his:
1) Admirable qualities and decisions
2) Philosophies, historical events or human beings that were a major influence
3) Personal conflicts or personality traits which caused difficulties
4) Personal obstacles which were overcome and influences which helped overcome these obstacles
5) Major mistakes and personal resolutions.
For the last one I'd say his drinking and smoking habits. He used to drink a lot during the JT era, and it became a problem in his house. I think Ali even kicked him out. Smoking damaged his throat, he even considered quitting his singing career. Didn't he stop smoking for a while?
