Exposure to black mold was suspected to cause a desire to drive off a road into a tree.

“I look up at the ceiling, and there's black mold right there on the ceiling in this Barnes & Noble, which is historically a pretty nice bookstore. And I go, "Oh my god, there's black mold. We got to get out." And on the way home, you know, we've got some pretty nice windy country roads. We're outside of the city, and there's some huge trees along the way. And I just had this small thought or wish that my wife would just run us off the road into the tree. And I wasn't suicidal. I just I was just done. I'm like, "I've had a great life. I'm okay to be done now." And then I snapped out of it. And I thought, "What is wrong with me?" And then she goes, "Honey, well, you were just at Barnes & Noble. Maybe it was the mold."”
