Those who dunk into a well of ketchup are methodical and trustworthy, but may also be control freaks who are afraid of change. Ambitious people drop their sauce in the middle of their food. Creative types squirt and swirl their sauce in thin lines, but deep down are impatient. Those who dot their ketchup are friendly, but live conservatively and dream of adventure holidays. Smotherers are the life and soul of the party, while artists who draw faces and words on their food have an easy-going approach to life. Gourmets who keep ketchup in a cruet appear charming, but deep down may be snobbish.
On average, each person consumes about three bottles of ketchup a year.
