Perhaps they gave him a minimal dose due to his age.
True. But I or my siblings were never told that. What that means is that someone made the decision to give the minimal dose, knowing full well the possible negative ramifications. What his age the determining factor? Does that mean they thought “oh well, he is so old, why would it matter anyway since he had a good life”, or along those lines. Was is a “mini-death panel” decision? I guess we will never know.
