According to a study in the Journal of Consumer Affairs, my generation doesn’t know much about how important sunscreen is to health and continues to sunbathe — particularly people with low self-esteem and narcissistic tendencies. The actual title of the paper is a thing to behold: I Know, but I Would Rather Be Beautiful: “The Impact of Self-Esteem, Narcissism, and Knowledge on Addictive Tanning Behavior in Millennials.” It’s easy to see write this off as another story in the vein of “Those darn millennials!” but the findings actually reveal a lot about a huge public health hazard, and help reveal a way to mitigate it in the future.
