The sudden death of Ken Lay raises the natural question of the link between stress and heart disease, indeed the link between overall health and overall behavior.
There does not seem to be conclusive evidence that a heart attack results from stress alone — say from having robbed thousands of people of their life savings, or say from the prospect of spending the rest of your life in confinement sharing a cell with someone named Bubba.
Although this blog is dedicated to presenting evidence showing how strongly behavior mediates health and illness, every once in a while, doubt creeps in, and one is forced to consider the effect of unquantifiable karma, or even prayer.
The sudden death of Ken Lay is one of those times.
