If the conversation people think is coming is the 'death panel' conversation, that's a total failure.

We have medicalized aging, and that experiment is failing us.

One of the reasons people might be fallible, why we might fail to do what we try to do isignorance, that we have a limited understanding of the laws of the world - the physical laws that govern the world and of all the particulars of the world upon which those laws work. And then there's ineptitude, meaning that the knowledge is available, but individuals fail to apply it correctly. The third source is "necessary fallibility." That is, we're never going to be omniscient, there is some knowledge that we will simply never achieve, and there are limits to what we will be able to do.

In psychology, there's something called the broken-leg problem. A statistical formula may be highly successful in predicting whether or not a person will go to a movie in the next week. But someone who knows that this person is laid up with a broken leg will beat the formula. No formula can take into account the infinite range of such exceptional events.

What about regular professionals, who just want to do what they do as well as they can?

A failure often does not have to be a failure at all. However, you have to be ready for it-will you admit when things go wrong? Will you take steps to set them right?-because the difference between triumph and defeat, you'll find, isn't about willingness to take risks. It's about mastery of rescue.

The definition of what it means to be dying has changed radically. We are able to extend people's lives considerably, including sometimes, good days.
