In what has already been dubbed the "best anti-smoking advert ever, a Chinese transplant surgeon has shared a video of his team

removing a blackened pair of lungs from a failed organ donor.

Doctor Chen Jingyu head surgeon of a transplant team, said the patient had died at just 52 years of age, after chain-smoking for 30 years The man wanted his organs donated, but the team quickly discovered that the blackened lungs were not remotely suitable for transplantation and that the lungs would not be of any use to a patient in need on the waiting list. They had been heavily blackened due to decades of tobacco residue accumulation, and are far from the pink colour expected from healthy lungs

The former heavy smoker's lungs showed all the signs of calcification, bullous lung disease and pulmonary emphysema, all tied to three decades of smoking.

The patient didn't undergo a CT scan before his death. He was declared brain dead, and his lungs were swiftly harvested shortly after that, before anyone could examine them, which is why they made their way to Jingyu's team. Initial oxygenation index tests were OK, but when they recovered the organs, the surgeons realised they wouldn't be able to use them and had to reject them because of their shocking condition, as the video shows.

Dr. Chen added. It would be impractical to say that we wouldn't accept the lungs of all smokers, but there are strict standards. These include lungs under 60 years of age in a patient who has only recently been declared medically dead; minor infections in the lungs and relatively clean chest X-rays are also acceptable. If the above conditions are met, we would consider transplanting the lungs.

September, there were four coordinated suicide terrorist attacks carried out by the militant Islamic extremist network al-Qaeda

against the United States on Tuesday, September 11, 200

That morning, nineteen terrorists hijacked four commercial airliners scheduled to travel from the northeast US to California. The hijackers crashed the first two planes into the Twin Towers of the World Trade Center in New York, and the third plane into the Pentagon (Arlington, Virginia Forces headquarters, The fourth plane was intended to hit a federal government building in Washington , D.C., but crashed in a field after a passenger riot

The attacks killed nearly 3,000 people and spurred the global war on terrorism. There were 2996 deaths, 2977 victims and 19 Al-Qaeda terrorists. There were also around 25,000 wounded. Plus at least $10 billion in infrastructure and property damage. It remains the deadliest terrorist attack in human history and the deadliest incident for firefighters and police officers in US history, with 340 and 72 dead, respectively. The destruction of the World Trade Center and its surroundings seriously damaged the economy of New York City and induced shocks in the global market.
