There is one more proof that video games such as the World of Warcraft is not only addictive but also fatal.

On Wednesday, 24-year-old Wu Tai from Shanghai entered an Internet café and played the newest installment of the game for 19 straight hours without a break. CCTV footage showed that he violently coughed up blood and then suddenly fell dead, reports Daily Mail.

But what is appalling about the situation is that despite coughing up blood and looking very sick, Wu insisted on still playing World of Warcraft.

Another young gamer who sat beside Wu, 20-year-old Hsin Lo, recalled hearing him groan and when he looked at the gamer, Wu was pale and wiping his mouth with a handkerchief that was bloodied. But Wu told Hsin he was okay.

Hsin was not convinced and called an ambulance, but by the time it arrived, Wu had died in front of fellow gamers. The paramedics still tried to revive Wu, but eventually declared him dead.

A police spokesman explain that after sitting for 19 hours, Wu developed deep vein thrombosis that moved to his lungs and became pulmonary embolism. But an autopsy would still be performed on Wu.

According to Mayo Clinic, deep vein thrombosis when a blood clot or thrombus form in one or more of the deep veins in the body, usually in the legs. It causes leg swelling or pain.

It happens to people with medical conditions that affect how their blood clots or for people who don’t move for a long time, like what happens to Wu.

Mayo Clinic warn, “Deep vein thrombosis is a serious condition because blood clot in your veins can break loose, travel through your bloodstream and lodge in your lungs, blocking blood flow (pulmonary embolism).”
