I think this is a very important study — really tight control is not just hard but deleterious.
“Results of a 22-year study by researchers at Cardiff University School of Medicine in Wales indicate that older type 2s who try too hard to drive their A1c’s down to “normal” (4.5% to 6%) may significantly increase their chances of early death. In fact, the study, just published in the British medical journal The Lancet*, found that type 2s with the lowest risk of death had A1c’s of 7.5% — a figure that few authorities on the disease have recommended as ideal.”
