What sport do you think is the most dangerous?

I don't know whether any of you guys have seen this but there is a sport called extreme ironing ... sounds far too dangerous for me :D :P

Though I never have done and will never attempt to try is reaching for the highest peak of Mount Everest... Hikers terribly encounters shortness of breath due to amall amount of oxygen in there as well as the great possibilities of frost bites like that of latest expiditions by the Philippine Team... Oh boy that is really tough to handle and I salute them all.

I think it is nascar or indy car racing.With other sports you may get hurt. but with car racing you may lose your life.

mix martial arts obviously since it is a contact sport.... referee always says "protect yourself at all times"

I think the Formula 1 should be the most dangerous one. This is because, all the drive in very high speed to win the race. When peoples in high speed, silly mistake will cost an accident. But today's technology, this sport has been embeded safety equipments so that the drivers will not affected too serious when any accident occurs.

I think boxing is the most dangerous sports. It is very harmful for people. I wonder why people will enjoy watching or participating it.
