This graph shows the relationship between the number of concussions retired football players had and the percentage of them that experienced depression. A total of 33% of retired football players have experienced some type of depression. Considering how many players there have been in the NFL, this number is very big. Many retired football players who have experienced several concussions have gone on to deal with severe depression and in some cases suicide has been the end result. This is an important graph because when these players suffered concussions their team doctors did nothing to help the problem. Today doing nothing is a very bad idea but 20 even 10 years ago players were told to play with the pain.
