"According to an experiment commissioned by Silverjet, which operates all-business class flights between London Luton and New York Newark, and conducted by the neuropsychologist David Lewis, the stress that passengers endure when traveling through Heathrow is higher than that of a Formula 1 driver during a race, a free-fall parachutist during a descent, or riot police confronting a stone-throwing mob.
"Heart rates and physiological stress levels of the travelers peaked at four times their normal resting levels during the trial," Lewis said.
So you may share my surprise to learn that Heathrow rates only third place, behind London Gatwick and Stansted in a league table of "British Airports of Shame".
Now you all know that I was not exaggerating!
