Concussions have become quite a common injury in high school sports. A 2011 study indicates that concussions account for around 15% of all high school injuries for schools with athletic trainers. I specify that these schools have athletic trainers because this injury is often difficult to detect. In 2012, the American Academy of Pediatrics presented a paper that suggests schools with athletic trainers post higher concussion rates than schools without athletic trainers. This is clearly a problem. High school students will not have the discipline or the awareness to put themselves out of the game if they do not have an athletic trainer. Thus, I propose that Elon Musk invents a device for all sports that can be used to detect concussions.
