I usually stay up pretty late, but not all night since we moved to Florida. Prior to that, I worked for an electric utility company and stayed up all night a lot. Most of the time, but not all, I got to go home and sleep the next day. In addition, I was a volunteer foreman for over forty years and would sometimes be up all night for a fire. To the best of my recollection, it's been almost four years since I stayed up all night.
