Working long hours is killing hundreds of thousands of people a year, according to the World Health Organization.

In a new study, researchers found that people working 55 hours or more a week are 35% more likely to suffer a stroke and 17% more likely to die of heart disease compared to people putting in 35 to 40 hours a week. That amounts to about 750,000 people a year across the world — and that was before the pandemic hit and rejiggered work-life balance struggles.

The evidence keeps mounting.
