Absolutely true. But that's the DB puzzle in a nutshell, isn't it? How do you convince someone who, by definition, doesn't want to "work" to "work" against the probability that the work won't, er, work -- at least from their POV?

"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
