Armature Pro-wrestling

There are many amateur pro-wrestling groups in our region. They perform in many places. I watched their performance on TV. They perform very well like reall pro wrestlers. The wrestlers are dentists, civil servants and office workers. 

I really like watching pro-wrestling, especially old style one. But I don't like amature pro-wrestlers because they are performing too much dangerous things. They even perform German suplex. That's a very dangerous performance. Someday, they would get serious damages on their body. If they get hurt seriously, how do they earn maney for live?
