The Mayfly lives only six hours! It gets its name from the fact that it hatches in the month of May. Yet the eggs of the Mayfly do not hatch for three years! A six-hour lifetime seems mighty brief, but then fourscore years and ten seem short to the human who has reached them. If we could compare our longest life-span with eternity, we'd have a real sense of perspective. We'd know what is important and what is insignificant. And we'd know how best to use our years.
