Why would you want to talk about death? Isn't that weird?
There is only one thing we can absolutely guarantee in this life, and that is that it will end in death. But the question is, how prepared are you? Does anyone (other than you) know what you want? Do you think that those you are leaving behind know what you want? I suspect in most cases that while you have given random thought to your death, that you haven't shared your wishes, and this is the difference between a good death, and one that leaves those who love you most with unanswered questions, and even anguish as to whether they honoured your life in a way that you reflected who you are.
Its never too soon to think about how you would like to spend your final days, put a plan in place and get on with life! Your family will love you for it!
