I was teaching a safety class about stress in the workplace at the union hall, my class was three apprentices, and I being a journey man revealed how great life was going for me at present. One guy remarked on it, so we got to a part about stress affecting the body and I brought up cold sores. Turns out I'm the only one in class who gets them when I'm stressed out, I turned to the guy and let him know his life wasn't so bad.
