It offends one's sense of proportion.

In a well-regulated universe there would be no tedious process of decay, either before or after death.

You would go about your daily avocation unconcerned and unwarned, and then at the moment appointed by an inscrutable Providence for your dissolution--phew!--and your clothes would remain standing for a surprised second, and then fall down in a heap without a particle of you inside them.

If we have to die, why doesn't Providence employ this simple and sensible method?
It would save such a lot of trouble.

It would be so clean, so painless, so picturesque.
