Surprising well but he has skewed memories that make it very hard on his family. We raised 5 in Alaska and they had an outdoors-men dream of a life which everyone remembers...except him. All of the little petty family problems are in his brain as these gigantic traumatic events. The camping, hunting and fishing are on the periphery and only come out as fleeting events.
His siblings try to break through with the truth and have a hard time understanding that the most complex wiring God ever created (our brain)is now “short circuiting”.
