At about three o’clock last night, down Devon way, it was quite a lot on the rainy side.  I woke up just before the rain came and knew without a shadow of a doubt that it was going to start because I am a human barometer.

Let me explain – you know how in stories, old ladies always say “I can feel it in my bones”?  Well since I broke my ankle, I actually can.  I have worked out that my bad leg (still call it that even after four years) starts to throb just as a weather front goes over. This means that approximately 30 minutes or so after the first twinge, it starts to rain.  Meteorologists feel free to point out the mistakes in my calculations here!

This is not quite the useful weather prediction tool that you might imagine it is.  For a start, I often forget about the leg phenomena until it actually starts to rain.  You know the feeling girls – you are grumpy and cry a lot for a couple of days and then realise that the whole, wide world is actually fine and Mr Month has come to visit again.  Another issue is that the time I need to know about oncoming rain is when I am out on Dartmoor.  As walking across Dartmoor makes my leg ache anyway, it is difficult to tell whether rain is on its way or not.

Take tonight (I am writing ahead again) as an example.  It is 19.51 and I have just had a left leg twinge.  I am sitting on the sofa so no exercise related pain … lets wait 30 minutes and see what happens …

20.08 – leg definitely murmuring at me but no rain yet…

20.15 – still no rain but I do need a wee…

20.20 – no rain, still aching and I really, really need a wee …

20.31 – oh no, am I broken, it is not raining at all …

21.07 – going out for a doggie bimble to check …

21.30 – back from bimble, no rain but very wet air, I think that counts …

I looked up an explanation and it is a bit complicated but basically to do with little pockets (trabecular) which, in a non-broken long bones have a standard negative pressure but in a broken then sealed bone, have a positive pressure.  This means that when the barometer drops, there is more pressure on the inside of the bone than on the outside causing pain sensation in pressure sensors.

Blondes doing science?  What is the world coming too?  They will be letting us loose with a computer next …
