Not quite as old as yourself; not had T1 quite as long either - but I was gobsmacked last year when one of my consultant's housemen snapped at me why on earth was I concerned about my HbA1c 'which is well within range!' I said because it's always in the low 50s and it's now 60 which is far higher than I've ever been used to - so what, pray, was my range supposed to be? 'Up to about 58ish of course!' she snapped back at me, with a look like I was a squashed slug she'd just trodden on. Condescending bitch. Nobody medical that I have ever seen had ever mentioned before her, that I'm not supposed to even aim for under 50 any more.
PS - I sincerely hope you survive without harm too!
