"How being sarcastic could kill you: Scientists reveal heart attack survivors with 'hostile traits' are more likely to die from a repeat event"
"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."
"Those who are hostile to others are also less likely to look after their own wellbeing - and more likely to smoke, drink and have poor lifestyle and diet."
"'Hostile individuals have increased clotting times, higher adrenaline levels, above normal cholesterol and triglyceride levels, and increased cardiac reactivity,' they said."
"And people with a positive outlook eat better, do more exercise and are less likely to drink."
