World's most horrifying ad ever

St John Ambulance has launched a bone-chilling video to urge people to learn basic first aid and save lives.
In the shocking campaign, a father is shown beating cancer only to choke to death at a barbeque party, reports Daily Mirror.

The video has been aired recently in front of millions shortly after 9pm during Downtown Abbey's ad break. It is one of the most expensive slots on prime time British television.

The 6- second clip shows the heartbreaking story of a young man being diagnosed cancer, going through chaemotherapy, losing hair and hope and bidding goodbye to family. But miraculously, he survives cancer and attends a barbeque party to celebrate his successful battle against cancer.

He then chokes on a piece of meat during the celebrations and gasps for brath as everyone looks at him helplessly and he dies for lack of emergency aid.

The daily says: "The St John Ambulance campaign comes on the back of alarming figures which show that 140,000 people a year die in situations where first aid could have helped – the same number as those who succumb to cancer."
