Well, there is a lot of weird stuff around the world. But I have never heard about extreme ironing. Probably, it was discovered by housewives who were bored with their chores. This what can make your day worth living: ironing at the top of a mountain. Cool, isn't it? But it is dangerous too, so think twice before you decide to do this.
