“Heart risk ’linked to working hours’”(NHS choices),

This news is based on a study that followed 7,095 British civil servants for over 10 years, examining how their working hours related to their risk of having a heart attack. Over the course of the study, 192 experienced a heart attack, with those working over 11 hours per day being 67% more likely to experience one than people working 7 to 8 hours.
