It’s a commonly quoted maxim that there are only two certainties in life — death and taxes. But while most of us have little control over the money the government rudely deducts from our wages, it is human nature to consider what might happen when our time on earth is finally up. Some of us might have already made a list of the favourite relatives we’d invite to our funeral or thought about the uplifting music we might play. Others might have considered a traditional burial or want their ashes scattered in a cherished beauty spot.
