It Is Not Work that Kills Men, But Worry

"It is not work that kills men, but worry.  Work is healthy; you can can hardly put more on a man than he can bear.  But worry is rust upon the blade.  It is not movement that destroys the machinery, but friction."
-Henry Ward Beecher

"Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God." Philippians 4:6
