There are things that can help to prepare as someone approaches the last few weeks and days of life. Having information can help to make choices.
People vary in what they know, understand and believe about death and dying. They also differ in what they want to know. Each individual should be as informed, or not, as they want to be. For many, knowing what to expect can help take some of the fear, distress and anxiety away. For others, having too much information gives them more things to worry about.
