Ah, the old hypoglycaemic ninja powers work every time against you mere mortals with your puny insulin-producing endocrine systems. Insulin-dependent diabetes means I've woken up in A&E many times as a result of low blood sugar, usually fighting the medical staff tooth and nail as they try to treat me. Apparently it once took six people to hold me down for a glucagon injection ... I seem to remember hallucinating that I was in hell and the doctors were white-coated zombies driving hot nails into my hands. So please don't complain too bitterly when a diabetic patient with 0.1 mmol/litre of blood sugar gets a little agitated - most likely he/she is (a) frightened out of his/her tiny mind and/or (b) totally unaware of his/her actions
