America and the world had many reasons t6 worry in 2003. First we faced the outbreak of a strange, contagious disease dubbed SARS. Although contained within months, the disease spread quickly from Asia to North America, killing hundreds and infecting over 4000 people. Next came the beef scare when Canada, and later the United States, reported its first case of the deadly mad cow disease. This was followed by a major outbreak of bird flu virus in Asia and the first case or avian flu on two different farms in the United States. We also witnessed the enormous popularity of Dr. Atkins, who instructed us to count carbs and eat fat in order to lose it.
