Rules of Sin

The biggest jerks on the road don't act any differently when they step out from behind the wheel, University of Minnesota researchers have found.
The most hostile people tend to react more aggressively while driving than their less hostile counterparts would, according to a study of 710 drivers aged 18 to 45 years. They're also more likely to drink and drive, take more road risks and show more anger toward other drivers, police and construction delays.

Another instance of modern society slowly catching up with notions of sin that monks and saints have understood for nearly 2,000 years. In this case, it's the fact that sin isn't isolated. If you sin in one area of your life (say, cheating on your wife), you're more likely to sin in other areas (cheating on your tax return). That's because sin proliferates.
