Study: Coffee may make you lazy
A new study has found that coffee may cause some people to avoid hard work when given stimulants like caffeine. Those that naturally want to work harder are not as productive when given caffeine as those who do not work as hard naturally. The study found that people who were motivated by small, rather than large rewards were more positively affected by stimulants.
