Gary Null is one of the great snake oil salesmen of our time. He makes unfounded claims, has dubious credentials, and sells products that mostly do no real good, or in some cases do some real harm. According to today's New York Post Null was almost killed by one of his own nutritional products, and is now suing its manufacturer.
Pause for a moment and take in the delicious irony. A fraud who almost dies from his own garbage. And then still has the stones to sue the people who make it for him. It reminds me of the guy who kills his parents and then throws himself on the mercy of the court because he's an orphan.
