PF he is referring to the change of life hot flashes. Being the male side of the species they just don't understand that it catches you completely off guard. The poor things don't realize that there is no time to set up the beer, the bath tub, etc. What is really needed is a nice cool swimming pool to jump into fully clothed if need be. Besides if the men did have hot flashes they'd want you to get up in the middle of the night to change the dripping wet sheets.
