A relatively unpleasant way to go, both for the person in question and those around him. You spend a lot of time with a lot of doctors telling you all the things you should do to eke out those last few days of life. They are not, as a rule, concerned so much with quality of life as they are with pure quantity.

Then, once you decide what treatment you really do want, you spend a few months slowly descending into complete incapacitation, while your loved ones get to attend to your increasing bodily needs.

It is said that it's easier on the next of kin if they have at least two weeks warning, but this whole process seems quite morbid. I prefer something quicker, if it's all the same to whover edits real life.
