Not really! But it is admirable the way they can sleep just about anywhere - like this!

I like Psalm 127:2:
"In vain you rise early and stay up late, toiling for food to eat - for he grants sleep to those he loves."But the passage I think missionaries need to bear in mind is Mark 4:26 - 28:
"This is what the kingdom of God is like. A man scatters seed on the ground. Night and day, whether he sleeps or gets up, the seed sprouts and grows, though he does not know how. All by itself the soil produces grain--first the stalk, then the head, then the full kernel in the head."
We can rest... it's God that makes the seed grow.
