Just in time for the Super Bowl, a recent Rolling Stone article examines the effects of concussions on young people’s brains. Although the article is behind a pay wall, a video discussing the effects of chronic traumatic encephalopathy, or CTE, can be seen here. When faced with the evidence from a doctor who specializes in CTE, one father responded “You haven’t convinced me. I’ll need more evidence than that.” It is amazing that when it comes to things like CTE or global warming that threaten the lives of our children or the future of our planet mountains of scientific evidence will not convince us of their danger. I suspect that many of these same people, however, would be outraged by a single picture of a shorter-than-average sandwich from Subway.
