Saraceno, Jon: Muhammad Ali, from the woman who knew him 40 years: His wife Lonnie Ali (I was somewhat stunned. I thought he should have been better off. Given the nature of who he was — and the people he was taking care of — it was understandable. Muhammad is not a businessperson. Muhammad did what he wanted to do. That is the nature of the man; that is how he got to be who he is. Fortunately, as he got older, a little bit smarter and wiser, he has been more prudent and frugal.) USA Today. 2010.
