in ancient times knights wack each other with sticks just for entertainment and sports, nowadays we do have that kind of sports anymore, we have something less brutal and violent, or is it? i think after reading articles and doing research i found out  that some sports caused a high rate of being injured or even death.  the 10th most dangerous sport is rugby, then motorcycle racing, golf, horseback riding,  football, cheer-leading, surfing,heli skiing(jumping out of a helicopter to ski) ,base jumping, cave diving . i chose the following by death rate and not by total number is because some sports is played by more people, and the number of death's will increase too.
  so, if we have such dangerous and high chances of getting injured, then why do people still do it? i think the main reason is because they are bored and wants to get excited or wants some thrill. and the other one i think is because they want to brag about it.
