SPLORE employees initially performed CPR on Halliburton, but the effort was stopped after Halliburton’s longtime girlfriend told them he had signed a “do not resuscitate” order and asked them to cease attempts to revive him, Mecham said.
I don't want to read too much into it, I think it's very interesting that he had a DNR (Do Not Resuscitate) in place. In my experience, the folks that have a DNR view themselves as close to the end, and are very aware of the type of end-of-life options they have. Not only that, but he included his girlfriend in that decision and she was brave & strong enough to reinforce his wishes under what could only be described as the most stressful of all conditions (mid-CPR). I cannot imagine how tough that was for her.
This would bolster the argument that Mr. Halliburton made an informed & calculated choice to live adventurously, despite his condition, in the short time he had left. That's an inspired life, IMO. A toast to you, Mr. Halliburton; rest in peace.
