thinking of afterlife is not really morbid in my view thinking that you do have an expiry date makes you think about what you are doing today.
I know coming from me it may seem strange, being the big bad liberal "mod" muslim and what nots, but thats what I think.
I meant morbid in the sense of thinking about who gets what and pulling of 'plugs'
Having been in the situation of 'when to pull the plug' and 'who gets what' Its just not nice.
However, I don't have 'real' possessions (im so sorry shoes, I do love you like my children) so I don't really feel that it is important to focus on them.
I do think that once I have a family of my own (ha!) I probably would consider these things, especially finances.
