Stuck in the middle of another COVID19 lockdown, that is quite a helpful thing to remember.  Perhaps we are already seeing positive signs.  Even in Belgium, one of the worse affected countries in Europe, almost all infection metrics have begun to drop over the last week.  The Reproduction Rate (R), deaths, hospital admissions, intensive care loading, and positive coronavirus tests are all lower this Friday than they were last.  To add to the good news, several vaccine projects look set to deliver working vaccines by the end of the year; a prospect the Prime Minister memorably described as the  coming of the scientific cavalry, even if we can, so far, only hear the far off toots of their bugles in the distance.
