" Yet more new studies prove we probably shouldn&amp;#039;t be drinking the stuff, this time because that whole &amp;quot;diet&amp;quot; claim is apparently worthless. So why does soda remain so popular? In Esquire&amp;#039;s August issue, Answer Fella discovers it probably has something to do with all the caffeine. Does caffeine added to soft drinks do anything other than wake us up? Well, there&amp;#039;s that and, of course, the marked increase in phallic girth. But wait: There&amp;#039;s more. According to Thomas Critchfield, an Illinois State University professor of psychology and coauthor of a study titled &amp;quot;Caffeine Reinforcement Demonstrated in a Majority of Moderate Caffeine Users,&amp;quot; &amp;quot;Caffeine makes us feel better. Stimulant drugs \u2014 including caffeine and close chemical relatives in coffee, tea, and chocolate \u2014 tend also to improve the focus of attention and enhance mood. Not only are we awake, but we tend to like the way we feel on caffeine.&amp;quot; Plus, Critchfield notes, &amp;quot;Caffeine is dependency producing.
