http://judojiko.net/eng/news/55.html These statistics are scary in general people die playing volleyball and table tennis in junior high?, how many junior high or high school students in the US do you think die from sports? I can think of only 2 I have heard of, one was a football camp on a 103 degree day, and the other is a basketball player who's father decided that they could ignore doctors orders and play with pneumonia.... It would be interesting for more statistics on circumstances of death? I'm wondering at least for kendo what percentage are hydration related vs well... what else would kill you in kendo? Freak broken shinai perhaps, heart condition manifesting during practice.....
