being a nurse, I have worked with a lot of people in the last few days of their life, keeping somebody comforable, clean and free from pain is the best area to start, it maintains their dignaty and self esteem. Secondly, helping take care of any issues that the individual has, even something as small as taking a house plant off them and looking after it can effect somebody’s happiness. And thirdly talk to them, don’t treat them any differently, the worst thing you can do is patronize them, make them feel important, help them to look at the positive things they have achieved and the positive impact that they have had on the world
