A survey of 7,000 California men found little correlation between alcohol consumption and chance of dying during the 5.5 years of the study. In fact, men who did not drink at all during these years had a slightly higher death rate than did light drinkers. This lack of correlation was somewhat surprising. Explain how common response might account for the higher death rate among men who did not drink at all over a short period.
A. Men who abstain from alcohol may have underlying health issues.
B. Light drinkers may engage in healthier lifestyle choices.
C. Men who don't drink at all might be exposed to other risk factors.
D. All of the above
