Yes it is tragic, but Bird is the wrong role model, wrong genre and wrong gender. He was never world famous, didn't sell millions of records and never made any money. The exemplars for Whitney were Edith Piaf and Judy Garland. Both were world famous divas whose troubled personal lives and abuse of alcohol and barbituates led to their deaths at almost the same early age: Garland was 47 and Piaf was 48. Both of their careers were seriously marred by the physical toll that their habits had on their bodies. Piaf actually died of liver cancer and Garland had advanced cirrhosis at the time of her barbituate-induced death. I could be wrong, but I wouldn't be surprised if the autopsy shows Whitney to have had a compromised liver as well, although that presumably wasn't the immediate cause of her death.Another truly great talent succumbs to "Charlie Parker disease."
You'd think that by now everyone would know that mixing pills and alcohol is really really dangerous, but obviously not. It's not just because it can easily result in accidental death--which is what it appears happened to Whitney, like to so many others--but because the combination wreaks double hell on the liver. If you look at the cause of death of many famous people who abused alcohol and drugs, some form of liver disease was involved in the decline of their health, if not the outright cause of their deaths. However you are right, this is definitely the same old sad song with just a different singer interpreting it.
