The reasons were vague to me. We knew they combined health and comfort, a commonsense intercourse among family members. I do not remember a time without them. None of us children ever complained to each other, nor put up a big whiny objection. They were humbling, but we counted that as good too, as our parents were ever held in highest respect when they were sober. When not sober we left them alone and stayed out of the way till it was over. Dad even would apologize the next day and let us know mom was going to help him live better, which i believe she did. She said to us and others, that she worshiped him because he rescued her.
So the enema was often appreciated as a kind of rescue, though that is not what she was referring to. He was a WW-2 Veteran and she, fatherless during the depression of the 30s.
Then someone asked or remarked here that, no doubt, enemas had left a certain mind set on our forefathers, as many of us are describing to one another on this discussion forum, as well. When my grand parents were in hospital, i was adult with children. Staying with them during their hours of trial was an honor to me. Grandmother was gone and he had been widowed 10 years when i gained opportunity to be with him that way. I was shocked, as he was receiving phone calls all through the wee hours of the morning. On the phone he entered into another world with his old friends. He was comforting people with his voice. Telling them when he got out, he would be right over to help them with that, but to bear with it on their own till then. After 2 days, i was able to connect the dots and realized he was practicing home health care, with those of his age that had lost husbands. He only had a telephone the last 20 years of his life. So this connection he was enjoying, with his elderly neighbors was huge to him and he had given himself to them all.
That, my friends, is the true story of enemas to me, not the jaded exaggerations of the entertainers, though some of it, i admit, is entertaining.
