I found this an interesting and informative addition to the recent Hubski Post Scott Adams from Dilbert on assisted suicide ... wow.
I've been in ICU. Only for approximately 24 hours, post craniotomy, for a surgical removal of a glioma (brain tumor). Yeah, I could see how having an informed position could definitely cause a person (a doctor) to go peacefully, rather than fight.
I made a tough decision that saved my life because I was properly informed. I had the great fortune of having some people close to me know a boatload about neurology and cancer. Because I had an informed position and the fortune to have a treatable condition, I chose a difficult path without hesitation.
Fortunately for me, my friends were able to inform me with absolute certainty, that a horribly painful procedure such as a craniotomy and it's recovery with follow-up chemotherapy was in my best interest. Only due to the fact that I had folks that provided me with the most honest and current information possible, did I go through with the surgery and risk it all.
It sucked, I faced the possibility of losing some of my sight and physical mobility, but I did come out intact.
Information is the key. Doctors know what they face. They make the tough decision.
