It has been a very strange year for me. I always tolerated heat very badly, 1976 was pretty horrible. Cold only worried me in that I have Reynauds and my fingers were not happy in extreme cold. Did not stop me riding motorbikes for many years. But, this last winter I really suffered with the cold. Chillblains all over my fingers and both hands and feet permanently cold, and no bikes involved. This heat has been a bit uncomfortable at times, but no real bother. Not like me at all! As for blood glucose, the heat seems to put it up slightly especially on waking up.
