I asked Marty, when working on this installation, what I could do, in my imaginary caregiver world, to ease his pain by assuming it for some period of time. One day a week? One month of the year? An hour a day? He replied that he didn't think I could deal with it, because of the severity. According to him, it is something that cannot be tolerated if one has the luxury of knowing what it is like to be pain free at least some of the time.
