This is a weird thought I had while driving over the M6 the other day. I now live near the M6. I can just about hear it on a good day, with the wind going in the right direction. I have to cross the M6 a lot. Every time I cross it, I look down at it and wonder where the people on it, at that particular time, are going. The other day, as I was crossing it, I thought how similar the M6 is to a vein in the body, the cars are blood cells and the people are bits and pieces within blood cells (I’m sure there are things in blood cells but I didn’t do biology beyond the age of 14).
Also, just like blood cells don’t live in veins, nobody lives on the motorway either. We are all transient travellers. We are always just passing by. There is no permanence on a motorway. It can be a very sad and lonely place. We might glimpse other people as we pass them, but we will most likely never see that person ever again. So like blood cells our cars are always travelling (despite the odd blockage of course). We don’t stop. We don’t stay. We just keep going, from one part of the body to another.
If motorways are like veins and the UK is the human body, that would make Birmingham the stomach, Manchester the heart and poor old London, the bowels.
