Coffee is one of the most popular drinks in the country, with almost two-thirds of Americans drinking at least one cup of coffee a day.

Hasan compared the data drawn from researchers and scientists over a number of decades to find out if the evidence overwhelmingly supports or opposes drinking coffee. The results gave Hasan a whole new perspective about data studies.
