Hmmm this is so touching and emotional.
Knocking that death is at the door isn't a pleasant news for anyone and I don't think we can never be prepared enough for it.
But then you've got a wonderful way to spend your last 24 hours which is with family and love one's.
Although has you've stated, it seems knowing when death would arrive is also a good thing because we get to share necessary information with our dare one's, we've seen many dies and their wealth go on discovered because they weren't opportune to share it before death came knocking.
If were in your shoes, I wouldn't have spent my last 24 hours any different, cause it'll also be spent around my family and reminiscing on old memories is such a great day to bid farewell has we appreciate the time We've spent together.
