20 or so years ago, back when I worked at farms, I read that people with Toxoplasma infections were overrepresented among those who were killed in traffic accidents[1][2]. [1]: this is a long time ago so my memory is a bit hazy, I cannot say for sure if it specified drivers or everybody who was killed in traffic accidents. [2]: Of course correlation doesn't imply causation, and this wasn't a research report but rather an ordinary book.
