Coffee drinking linked to reduced death risk


 So today, in health news that makes me happy (for once!), a recent study links coffee consumption with reduced death risk. The study followed 400,000 adults for 14 years and found that men and women who drink 4-5 cups of joe a day had the lowest death risk - 12% less than non-coffee drinking people. Even a daily cup of coffee reduced the risk of death compared to non-drinkers by 6%. Good news for those of us who have a rough morning without our daily dose of caffeine (although the correlation still exists for those who mostly drink decaf, suggesting that caffeine itself is not beneficial in this way).

Just a note: As usual, science reporting generally goes for the sensational above the technically correct. The statement that "Coffee may be the key to living longer" accompanying the above article is misleading because it implies that drinking coffee causes you to live longer, while the study has not proved that at all. Repeat after me, science scouts: "Correlation does not imply causation!"
