Well.... Most insulin dependant diabetic would get on with their lives as best they can and I too have done some of my injections just like Paul. If I can, I test bg first but it depends where I am, what I am doing and what people I have around me. The last thing I want is to make others feel sorry for me because they see me prick my finger for blood and get out a meter and then decide how much insulin I need and then inject. For all we know, Paul might well have cgm or if he hasn't, maybe he tested bg in another room before eating and injecting and that wasnt filmed. I don't take a pen needle off directly after injecting as not sure where I would put it anyway so just take pen needle cover out of my mouth (front teeth are brilliant), inject and then quickly replace needle and put pen cover back on and sling pen back in my bag and try to behave like a normal person even though I am diabetic.
Let's not chuck stones as we all need to live as normal a life as possible. Thank goodness hypoglycaemia hasn't been filmed in all its wonderful splendour using real life diabetics
