Shorts

I went out to dinner last night and the weather was freezing cold. I dressed in layers with a fleece top, a fleece jacket and then my down coat. I was stilled chilled as I got into and out of the car. As we were parking, I noticed a man coming out of a store. He looked to be in his late sixties, early seventies. He was dressed in a tee shirt, shorts and boots. He was walking slowly to his car as if the brutally cold weather did not affect him. Was he crazy or did he have no nerve endings?
