Indonesian copywriter Mita Diran, 24, tweeted about working nonstop Saturday, collapsing soon thereafter and dying the next day.
Many rushed to Twitter to lament her death and offer their condolences.
Her death is being blamed on overwork and oversonsumption of energy drinks.
It was not immediately clear what medical issues caused Ms. Diran's death, or even if they were related to work, though some local reports blamed her long hours and heavy consumption of a Southeast Asian energy drink. But the death struck a chord, particularly since it came seven months after a 24-year-old Ogilvy PR staffer in Beijing, Gabriel Li, suffered a heart attack and died at his desk. News reports quickly blamed his death on overwork, though the cause was not clear.
