Ow. I have learnt something new today. Giving blood does not hurt. Reaching for the dictionary to check "insensate" means what you think it means a couple of hours later does. This is, I suspect, due to the sticky plaster in the crook of my right elbow beneath which is the promise of a neat bruise. It has already meant I am drinking tea with my left arm (the one which only had a hb test done in its crook) and having to use my middle instead of my index finger when left-clicking on the mouse (due to the initial hb test). I knew in advance about the potential bruises and faintness, even remembering to have a good chunky pannini for lunch to reduce the shock. I knew about the tea and biccies. No one told me there might be dictionary reach pain.
And insensate does mean what I think it means: it means unfeeling.
