Last night, I drove to my dance class, and I drove home again. And on
both journeys, the monitor went crazy just as I drove past a specific
roundabout. I have no idea why, but that seems like one hell of a
coincidence...

If I do a "harcore" cycle ride for an hour or so my average is usually about
155, which seems inside the 152-171 zone identified by that chart for my
age.

Spurious electrical noise from things switching on/off?

High voltage electric cables above or below the ground? Or a train line?

I thought your heart rates were determined by your current level of
fitness rather than just your age.

In fact, I seem to remember it happened to be that same location the
*first* time I noticed it go wrong in the car too. So that's three
malfunctions, all on the same road. Certainly sounds like an
interferrence problem, doesn't it?

I am not an expert, but I think those ranges for the different sorts of
exercise are just depending on your age. How much actual work you have to
do to get your heart rate in to those ranges will depend on how fit you are.

Actually, the ranges are some percentage of your maximum heart rate. If you
don't care to measure your maximum heart rate, then you can use a chart and
assume you have a fairly average maximum heart rate.

You may call that "natural" but then it is not the same nature as animals,
is it? ;)

True, and you could say that human behaviour is not "natural" anyway.

Please explain what "unnatural" means, other than being synonymous with
"human behavior"?

Not natural and unnatural and not the same. :-P
I meant that we (humans) modify our behaviour for our overall benefit.
For instance a dog will overeat until it cannot easily stand then
continue to eat. Whereas we will diet.*
Well that is the theory.

Amusingly (or not?) even when I dance "normally" I hit 180 BPM or so.
Now I can understand that when I go out and utterly dance my socks off,
I might hit a high number. But even when I'm dancing comparatively
casually in class the numbers aren't all that much lower. Interesting...
