When is medical treatment too much treatment?

I thought the following article was interesting. It argues that in the USA the medical industry prolongs life with expensive sometimes "unecessary" treatments. It proposes that time spent in peace within a palliative care environment is a better way of approching the end of life than through the continuouse struggle against death. I wonder if as a society we are able to move away from the culture of the beautiful and healthy, and accept that aging, and dying is the full completion of the cycle of life. Happy reading. Please post comments if so inclined.
