We smart slaves have learned to sleep on our crossed arms, chest down. That way, the open sores from the lashes across our backs don't get dust and dirt in 'em.
... This has been another handy tip from the Smart Slave for all those other smart slaves out there. Keep on doing what smart slaves do! Toe the line. Keep your head down. Trust in the inherent benevolence of our masters. Learn how to mitigate the pain. And, most importantly, never fail to rat-out all the trouble-making stupid slaves who refuse to stay quiet and who refuse to believe in the never-ending final reward that is promised by the religion that was invented by our masters!
