Care and support
People may need quite a lot of physical help and support during this time, as they get weaker and less able to do things. However, a lot of the time they may just want to lie still and may want other people to just sit with them, without necessarily having to talk.
Occasionally, a dying person stays aware and able to talk right up until very close to the end, and can have a meaningful conversation with people around them. However, this is the exception rather than the rule, and it is important to say all the things that you want to at an early stage.
