Maybe you’re too hyper to kill yourself, But, seriously:
According to a new study by the Harvard School of Public Health, subjects who drank two to four cups of coffee daily were 50 percent less likely to commit suicide. This was observed in comparison to those who drink decaffeinated, very little, or no coffee.
Researchers examined data from three U.S. studies evaluating coffee and overall caffeine intake every four years. This included 43,599 men enrolled in the Health Professionals Follow-Up Study (1988-2008), 73,820 women in the Nurses’ Health Study (1992-2008) and 91,005 women in the Nurses’ Health Study II (1993-2007). The subjects shared information about their caffeine intake via questionnaires, and the studies involved 277 cases of suicide.
