Sarcastic and irritable people may be putting their heart in danger, research suggests.
A study of 2,300 heart attack survivors in the US found those who displayed hostile character traits – including sarcasm, cynicism, resentment, impatience or irritability – were at much greater risk of dying of a second attack within the next two years.
Researchers believe this may be because the emotional state of being consistently negative puts a strain on their health.
