You either get used to it or pay the psychic cost of carrying the dread around with you. Most people get used to it. I remember being on a fly fishing trip with a friend a long time ago. A friend was wading a river when he got a cell phone call. He was able to solve the problem while standing in the river. That was something new.
I was in a bad mule wreck some years ago. It required some power tools to put my femur back together. My doctor was supposed to be on vacation, but he showed up at 0300 for the surgery. I just wrote him and thanked him again after 11 years.
