It's very interesting and simple to understand info about concussions. People can get it in any situation, and others need to know how to help. I've done the research for my college, with the help of https://phdessay.com/free-essays-on/concussion/ about this, and have been surprised that many people haven't any idea what to do in such cases. I think that students should learn how to provide first aid as it can help to saves someone's life.
