    I'm a little confused by numbers that shouldn't be that divergent if the groups were properly randomized.
    When discussing coffee, the article states "The percentage of current smokers was 17% for non-drinkers"
    When discussing tea, we see "One-third (34%) of the non-drinkers of tea were current smokers"
    This discrepancy between avoidance groups requires greater explanation.
