When the health media is playing a game of Telephone, information can spiral out of control as writers and editors fail to read the medical-journal fine print. In this week's example of people who skimmed a study too quickly, some folks on the health beat of various publications claimed a correlation had been established between a weak handshake and a weak heart. The cardiovascular connection, though, was between handgrip and heart health, not handshake strength. So there's no need to pull the next clammy-palmed person you meet aside for a cholesterol intervention. Just take popular health stories with a grain of (low-sodium) salt.
