I think that
resting heart rate is as different for different people as
maximum heart rate is.
Comparing yours with other people's is a bit of a waste of time, but comparing your rates on different days
can tell you something. For example, it might go down steadily over a period of months as you get fitter. Going up over a day or two could be a sign that you are getting ill*** or overtrained.
When I was very fit and slim, mine was 34 bpm. These days it is probably 50-odd, though I haven't checked it recently.
*** Mine once went up to 150+ bpm for no apparent reason and stayed there for many hours. I should have taken more notice of that...
