Mono Monday: High/Low

A Mono Monday theme of 'High or Low'.  I was a bit lost for inspiration on this one but then thought of my blood pressure.  It can be a little high; not high enough to need any treatment but it's worth keeping an eye on it from time to time to check it's OK.  I tend to look at it over a period of a couple of weeks as, at first, I always seem to get high readings but after a day or so they settle down.

Being a bit of a nerd I have written a spreadsheet for the results which works out the average for each day from the highs and lows.  Just need to add a running weekly average!
