This sounds pretty ridiculous. According to the article he would have started smoking in 1973 - weren't the consequences of smoking pretty well known by that stage? And he continued smoking until his death in the mid-90's when the consequences were clearly known and he was old enough to make his own decision to continue smoking.

Also, how the hell did they come up with that figure? She's now one of the richest people in the world because her husband ignored well known health warnings.

I must be misreading it, how can it be 23 billion dollars?

I should get in the litigation line. Maybe I can win eleventy-zillion dollars!
