Twitter can predict hot spots for coronary heart disease

A new study, published in the journal Psychological Science, showed that Twitter not only predicts heart disease risk as well as many traditional factors, but it also acts as a psychological barometer.The researchers found that expressions of negative emotions, such as “hate”, “bored”, and expletives, in local community tweets were associated with higher heart disease risk, even after variables like income and education were taken into account. However, words like “wonderful” and “friends” were associated with lower risk.
