I have a friend whose grandfather lived to be 94. When he passed away, the man had hardly any wrinkles, and he didn't have a single gray hair on his head. I have no science to back this up, but I do believe it's the stress of driving that makes a person old.
Road rage can take many forms, from the merely cranky to the extremely dangerous.
The motorists who responded to The Automobile Association's survey reported aggressive tailgating, flashing of lights, rude gesturing, deliberate obstruction, verbal abuse and even physical abuse. Exercise extra caution on main roads where the majority of road rage incidents take place. If you're being hassled by a driver, don't react. Avoid making eye contact, which is often interpreted as confrontational. Don't retaliate by accelerating, braking or swerving.
